    Modbus Register Map 8.10 Time setting The PEM333… provides two time display formats: 1. Year/Month/Day/Hour/Minute/Second register 60000…60002 2. UNIX time register 60004…60005 When sending the time via Modbus communications, make sure to use only one time display format of the two time register sets. All registers within a time register set must be written in a single transaction.

  • Page 95: Dox Control

    Modbus Register Map 8.11 DOx control The DI control register are implemented as "Write-Only" registers (WO) and are set with the function code 0x05. In order to query the current DO status, the register 40066 has to read out. PEM executes commands to the outputs in two steps (ARM before EXECUT- ING): Before sending an open or close command to one of the outputs, it must be activated first.
