  • Page 159: Time Setting

    Modbus Register Map 10.18 Time setting There are two time register formats supported by PEM575: 1. Year/Month/Day/Hour/Minute/Second register 9000…9002 2. UNIX-time register 9004 When sending the time via Modbus communications, care should be taken to only write one of the two time register sets. All registers within a time register set must be written in a single transaction.
  • Page 160 Modbus Register Map PEM575 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 out- puts, it must be activated first. This is achieved by writing 0xFF00 to the appropriate DO register.
