Communication Function

MODBUS Communication setup
n
ZR802G has a MODBUS function. RS485 communication and Ethernet (MODBUS TCP/IP) are
available by specification of the model of ZR802G.
Here, setup it according to your hardware configuration. For MODBUS communication, refer to TI
11M12G01-62EN.
RS485 Setup (RS)
l
MODBUS communication using RS485 is available.
Preset "MODBUS address", "Baud Rate" and "Parity" from HMI according to the connected
MODBUS master.
Setup according to your MODBUS communication requirements
Converter addressing
Transmission speed
Parity
The stop bit is 1 bit when the parity is "even"/"odd", and 2 bit when the parity is "none". It is
recommended to setup the parity to "even" or "odd".
(1) "Converter menu" > "Maintenance" > "Communication settings."
(2) Select "MODBUS setting" to setup

Ethernet setup (E)
l
Modbus TCP/IP communication is possible by connecting master devices with an Ethernet cable.
Communication standards
Session times (Up to.)
Protocol
Port number
The communication rate corresponds to Ethernet 10/100 and Protocol corresponds to Ipv4.
To assign an IP address automatically by DHCP, set "DHCP" to "On". To use a fixed IP address,
set "DHCP" to "Off" (default).
If you are using static IP addresses, setup IP addresses, subnet masks, and default gateways
appropriately for your Ethernet environments. Ethernet setup parameter has the following default:
Parameter name
DHCP enable
IP Address
Subnet Mask
Default gateway
1 to 247(default 1)
9600 [bps], 38400 [bps]115200 [bps] (default 9600 [bps])
Even, odd, none (default even)
