Introduction
TCW242-S is an industrial IoT (Internet Of Things) module with Ethernet connectivity and data logging
capability. All monitored parameters can be seen as numbers and as graphs.
The device has 4 digital inputs, 4 analog inputs, an RS-485 interface for MODBUS RTU sensors, and 4
relays. The analog inputs can be switched either in a current loop (0 to 20mA) or voltage (0 to 10V)
modes. The relays can be activated remotely (WEB, SNMP, MODBUS TCP/IP, or HTTP API command) or
locally - from the alarm conditions.
TCW242-S supports up to 24 Teracom and third-party MODBUS RTU sensors.
The user can arrange up to 24 independent monitoring channels from the inputs and sensor readings.
Every channel can be set up using up to 2 input parameters and/or constants. There are two types of
channels – discrete (for OPEN/CLOSED outputs monitoring) and general (for general monitoring).
The user can also arrange up to 24 independent alarms with 5 different user-selectable states. Every
alarm can be set up using up to 2 limits and hysteresis. The alarm can be assigned to a specific channel.
In this case, in an alarm state, the assigned channel is colored on the monitoring page and graphs.
The device supports SNMP, HTTP API, and MODBUS TCP/IP protocols for machine-to-machine (M2M)
communication.
