    Modbus Register Map 8.11 DOx control The control register of the digital outputs are implemented as Write-Only registers (WO) and can be controlled with the function code 0x05. In order to query the current DO status, the register 0081 have to be read out. PEM533 supports the execution of commands to the outputs in two steps (ARM before EXECUTING): Before sending an open or close command to one of the outputs, it must be activated first.
