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.
