Ethernet ECC21 communication card
The ECC21 is an optional Ethernet communication card. It may be installed in the
slot in the circuit monitor intended for options. It has two main functions:
b equip the circuit monitor with a fast Ethernet connection over a 10/100 Mbits/s
copper link or a 100 Mbits/s fiber-optic link
b serve as an Ethernet gateway for devices daisy chained to its RS 485 ModBus
port.
The ECC21 card also includes a server for six HTML pages that may be consulted
by a standard web browser. These pages can be customised using WPG software
and display information from the host circuit monitor and/or devices connected to its
ModBus port.

IOC44 card
The IOC44 is an optional input/output card equipped with:
b 4 digital inputs 20 - 138 V AC/DC
b 4 digital outputs, including 3 relay outputs and a static output that may be
programmed as a pulse output.
Status changes on the digital inputs are time-stamped to within 1 ms. The IOC44
card may be installed in the option-card slot of the circuit monitor and may be used to:
b monitor the electrical installation, notably the status of the circuit breakers, and
check discrimination between protection devices
b measure the consumption of other commodities by counting the pulses sent by
water or gas meters.
