Comment: The “note” box on describes a deadtime rule that is different than the deadtime rule on Pg 14 of 310401C (Feedforward Control). While both rules are correct, it would be less confusing and easier to remember if a single general statement was referred to by both ILMs. Preferably the notes should both be “If the dead time of the process is larger than the dead time of the disturbance, the dead time parameter is zero.”

Comment: The last paragraph states: A flooded condenser control strategy is used when the coolant flow rate is constant and cannot be manipulated. The figure above shows the flow can be manipulated, it has a flow loop on the coolant flow. Shouldn't this be removed from the drawing to show there's no way to manipulate the flow? If this is removed, the sentence talking about the flow loop below the drawing should be removed as well.

Comment: The paragraph starting with the sentence, "The 2oo3 architecture has two degrees of HFT" is incorrect. A 2oo3 architecture can only have one degree of HFT, just like page 27 states for the sensors. Only a 1oo3 or a 2oo4 system could have two degrees of HFT. This also make the explanation in paragraph for a 2oo3 system incorrect as well. The first sentence should be corrected and the rest of the paragraph removed.

Comment: Pages 24 - 29: It would be helpful to show the calculation involved to find PFS and PFD for the different redundancy architectures as well as a general explanation of the rules involved. Example: If both devices must fail at the same time it is an AND function the PFDs or PFSs must be multiplied. If either device can fail but no necessarily at the same time, it is an OR function and the PFDs or PFSs are added.

Comment: ILM 310402b (Communication Signal Converters) only has 11 pages of material whereas ILM 310402aA and 310402aB (Signal Transmission Systems) have a total of 77 pages. The outline indicates 6 hours should be spent on both of these sections. Either the hours should be adjusted to 10 and 2, or some of the material should be moved around. Pages 34 - 47 along with the applicable question could be moved to objective 2 in ILM 310402b. RS-485 and USB are often part of a signal converter and could be discussed here instead. This would change the page count to 64 and 24. Fiber Optics and radio-wave communication often require a signal converter as well, so pages 14 - 32 from ILM 310402aB could be moved to objective 3 in ILM 310402b. This would bring the page count to 46 and 42. Note: Some adjustments to the material may be required to better integrate it into the 310402b ILM.

Comment: The direct addressing described in the ILM is very similar to the direct addressing used in Allen-Bradley's SLC-500 PLCs. It appears the ILM attempted to use the SLC-500 addressing, but got it wrong. A discrete input in slot 4, word 0, bit 3 would be written as I:4.0/3, but in the ILMs have it written as I:40.3. An analog output in slot 5, on word 2 (channel 2) would be written as O:5.2, but in the ILM it would be O:52. Adding the "/" and "." to the discrete and analog addresses would provide more clarity.

For a Boolean action, there is no bottom rectangle on the action and the items listed in the rectangle go in the following order from left to right in the action: qualifier, action name and Boolean variable. Ex: | S | Action_1 | Motor |, this action would turn on motor using a stored (S) qualifier. The ILM would show this with Action_1 written in a rectangle above and Motor (S); in the bottom rectangle of the action.

Comment: This page should also mention the non-Boolean action before discussing the non-stored (N), stored (S) and reset (R) qualifiers. The non-Boolean action can include multiple lines of structured text like the example in figure 52 on page 45. Figure 52 is comparing two non-Boolean actions one using a non-stored qualifier and the other using a pulsed qualifier. The other type of action is the Boolean action. This action has no option for structured text statements. All of the actions shown in figure 49 are Boolean using the stored or set (S) qualifier and the reset (R) qualifier. Both ControlLogix PLCs and DeltaV all the user to set the action to either Boolean or non-Boolean.

Comment: There should be more information added to the HART_FIELD_VAL variable. When this variable is used, it allows the DCS to write the XD_SCALE or OUT_SCALE range values and corresponding engineering units to the HART transmitter. If an Indirect or Indirect Square Root L_TYPE is used, the XD_SCALE will be written and if a Direct L_TYPE is used, the OUT_SCALE will be written. For any other parameter (FIELD_VAL_PCT, HART_PV, HART_SV, etc.) the DCS will not write the range values or engineering units to the transmitter. This is stated in the following white paper and was verified on a DeltaV control system: http://www2.emersonprocess.com/siteadmincenter/PM%20DeltaV%20Documents/Whitepapers/WP_HART_Capabilities.pdf

Comment: Figure 7 has the OUT parameter on the AO_1 block connected to the BKCAL_IN parameter on the PID_1 block. It should actually be the BKCAL_OUT parameter on the AO_1 block connected to the BKCAL_IN parameter on the PID_1 block.

Comment: In the in VLVNC-12 control module found in the DeltaV's library, it suggests using IO_IN1 for closed status (ZSC101) and IO_IN2 for open status (ZSO101). This is opposite of what's described in the fifth and sixth bullets under figure 27. Please have this changed to match what DeltaV recommends.

Comment: The expression statement in CND_2 must be written as: '//HC101/DC_1/PV_D.CV' = 'VLVNC-PV:CLOSED'. This would be the correct expression for this to work in DeltaV. The ILM refers to the PV parameter in the DO_1 function block, but there is no PV parameter in a discrete output (DO) block, it's a PV_D parameter. Also, the PV_D parameter in a discrete output (DO) block can only be "0" or "1". It's the PV_D parameter in the device control (DC) block that references the VLVNC-PV named set with the option to be CLOSED or OPEN. The named set is a location or file that stores text values used by the DCS.

Comment: In DeltaV, a device control (DC) block does not have a BKCAL_IN_D parameter, so the BKCAL_OUT_D parameter of the discrete output (DO) block would not be connected. Could not find this in any literature? Remove the bullet about connecting the BKCAL_OUT_D to BKCAL_IN_D in the third paragraph. Also, remove the BKCAL_IN_D parameter and its connection from the DC block in the following three figures: figure 25 (page 37), 26 (page 38) & 28 (page 40).

Comment: In figure 30, the STATE_MASK Properties diagram uses a radio button (checkbox) to indicate a TRUE or a FALSE value. According to the ILM, if the radio box is checked, this means it is looking for a FALSE value and if it is not checked, this means it is looking for a TRUE value. DeltaV does the complete opposite. If the checkbox is checked in DeltaV, it indicates a TRUE value and unchecked indicates a FALSE value. Also, in the STATE_MASK properties for DeltaV, the passive states are listed on top and the active states below. Switch the text for passive and active in figure 30 so passive in on the top. Assuming the ZSC101 is now connected to IO_IN1 and the ZSO101 is now connected to IO_IN2 (refer to change on page 42) use the following settings for passive: IO_IN1 = "checked", IO_IN2 = "unchecked" and IO_OUT = "unchecked". Use the following settings for active: IO_IN1 = "unchecked", IO_IN2 = "checked" & IO_OUT = "checked". Change the description in the bullets above and below figure 30 to match the changes in figure 30.

Comment: In figure 34, just the text for passive and active need to be swapped. In DeltaV, the passive states are listed above the active states. Just switching the text will also make this figure correct with the three paragraphs describing it above. Checked should represent energized and unchecked should represent de-energized.

Comment: The expression statement in CND_2 must be written as: ‘//HC101/DC_1/PV_D.CV’ = ‘VLVNC‐PV:CLOSED’. This would be the correct expression for this to work in DeltaV. The ILM refers to the PV parameter in the DO_1 function block, but there is no PV parameter in a discrete output (DO) block, it’s a PV_D parameter. Also, the PV_D parameter in a discrete output (DO) block can only be “0” or “1”. It’s the PV_D parameter in the device control (DC) block that references the VLVNC‐PV named set with the option to be CLOSED or OPEN.

Comment: In figure 7, the rotation of the armature is incorrect. According to the right-hand rule used for conventional current flow and the direction of current flow in the diagram, the magnetic field produced by the armature would generate a north pole on the bottom and a south pole on the top. Opposites attract, so the rotation would be the opposite direction from what the diagram shows.

What is described, is a point-to-point topology which is where only two nodes are connected on a network. See link: http://www.conceptdraw.com/How-To-Guide/point-to-point-network-topology. The heading on page 38 along with wherever it says peer-to-peer in the paragraph should be changed to Point-to-Point.

Comment: In figure 21, the second three-way valve from the left for both stream 2 and 3 should have the left and bottom port white and the right port black. This would ensure the bleed path releases pressure between the two valves when blocking sample flow. The second paragraph below figure 21 states the purpose of the bleed path is to bleed this trapped pressure, but with the way the three-way valves are currently drawn this will not happen.
