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.
Application of Serial to Ethernet RTU ZHC1931
