MODBUS Registers
The following tables define the available MODBUS
registers and coils.
Process Data is obtained from or written to attached
(or internal) I/O modules. The location of each
value can be determined through the formula in the
Register Reference column. Each module is allocated
8 adjacent registers. Analog modules treat these
registers as 4 adjacent floating point values. Discrete
modules use a 0 or 1 in these registers for each
variable.
Channel Status is read from each channel, and is
stored in the MODBUS map at the specified location.
Each module is allocated 4 adjacent registers. For
analog modules, each register corresponds to a
channel. For Discrete modules, the first register
corresponds to the module status.
