Supported M2M protocol – SNMP v.1 makes the TCW181B-CM good choice for controlling systems with SNMP manager software.
Ethernet digital IO module supports one digital input, which can work either in “dry contact” or “logic level” mode. The mode is hardware settable by jumper, close to the input.
Every change of status of the input can generate an e-mail or SNMP trap if this function is enabled.
