  • Page 83: Time Setting

    Modbus Register Map 8.10 Time setting There are two time register formats supported by PEM533: 1. Year/Month/Day/Hour/Minute/Secondregister 9000…9002 2. UNIX-timeregister 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.

    (WO) and can be controlled with the function code 0x05. In order to query the cur- rent 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 out- puts, it must be activated first.
