Communication
- Ethernet modules are covered by IEEE802.3 standard and supports ARP, ICMP, IP, TCP, UDP protocols.
- There is No limitation number of Ethernet module installation in one base but the maximum number of expansion modules in one base is 11 modules.
- It operates with CIMON-SCADA to support Dynamic IP(DHCP).
- It supports MODBUS/TCP Master function.
- It supports High-speed link to communicate along Cimon PLCs and 64 simultaneous communications.
- In case of High Speed PLC link, maximum 4 Ethernet modules can be installed.
