On the next pages, find the module type that corresponds to the type of Modbus slave I/O you added to the TCU.
• digital inputs = DMM
• digital outputs = DCM
• analog inputs = AMM
• analog outputs = ACM
Then, find the column for the module letter the I/O was added to. Each of the modules (H-O) can accomodate:
• Twelve (12) digital status registers, or
• Eight (8) digital control registers, or
• Four (4) analog status registers, or
• Four (4) analog control registers
For example, if you added 4 (four) digital inputs to module H, you would select the first four registers listed in the module
H column of the DMM Module Type table (14337, 14338, 14339, 14340).
