Parameters of Serial to Ethernet RTU ZHC1931

Introduction​ of Serial to Ethernet RTU ZHC1931

ZHC1931 is a network IO product that supports 2 dry (wet) node detection, 1 relay (COM, NO) output, 1 analog (current 4-20mA) detection, and 2 serial port transparent transmission. It is compatible with Modbus RTU/ TCP protocol.
With "remote control" as the functional core, it is highly easy to use. Users can easily and quickly integrate into their own systems to realize remote and local control based on Ethernet and RS485/RS232.

ZHC1931 DI supports active reporting, periodic reporting, etc.

DI voluntarily report description:

After power-on, if there is no DI status change, it will be reported cyclically for 60s (0x003C). If there is a DI status change, all statuses will be reported immediately and the cycle time will be reset.

AI voluntarily report description:

Disable reporting mode: Report all AI values cyclically according to the set cycle.

Report within the interval: When the set AI channel value enters the interval from outside the interval, all AI channel values are reported immediately and the cycle time is reset.

Report outside the interval: When the set AI channel value enters the interval from inside the interval, all AI channel values will be reported immediately and the cycle time will be reset.
