Figure 6.10 shows the terminal block labeling of field connections. All modules follow the convention of labeling
bottom side plugs from A to C as the staircase to the top and D to F for the top side plugs as they staircase to the
top. Numbers one through 4 are arranged from left to right when viewing the plug from its wire entry side. To
differentiate terminals of different modules, Toptech recommends a
module.slot.number
identification scheme
where
module
is the FCM’s address,
slot
is either 0 or 1 depending on whether the terminals are attached to the left or right board in a double wide
housing, and
number
is the terminal A to F, 1 to 4.
As an example, an ANALOG/4DCIN/4ACOUT module at address 0, would have its Port 0 line voltage terminal
labeled 0.0.A1 and the loop voltage for the RTD would be labeled 0.1.D1. See Figure 3.5.
