7�3�4�- COMUNICACIONeS MODBUS
The address of the Modbus memory map depends on the position of the expansion module in
the unit.
Slot 1 will be the position of the expansion module installed just behind the standard unit, and
Slot 2 the next position...
As the maximum number of expansion modules that can be connected to the unit is 4, there
will only be 4 slots.
7�3�4�1� - Programming of transistor digital outputs
The following functions are implemented for these variables:
function 0x04: reading registers.
function 0x10: Writing multiple registers.
