The MasterPact MTZ is a high-power air circuit breaker equipped with the MicroLogic X control unit. It provides advanced energy monitoring and protection.
The driver supports the MasterPact MTZ range (MTZ1, MTZ2, MTZ3) when communicating via Modbus RTU.
| Device Type | Modbus TCP (Ethernet) | RS485 |
|---|---|---|
| MasterPact MTZ (MicroLogic X) | ❌ | ✅ |
Important: MicroLogic X Required This driver interacts with the MicroLogic X control unit. Ensure your breaker is powered and the control unit is active (The "Ready" LED should be blinking green).
Interface Module Required The MasterPact MTZ communicates using the internal ULP protocol. It does not have direct RS485 screw terminals on the breaker itself.
To connect it to the Sofar EMS via RS485, you must use the EcoStruxure IFM Interface (Ref: LV434000).
| Device | Sofar EMS model OM1 | Sofar EMS model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| D1 (+) | RS485 A | RS485_POS | RS485 A | TX+ |
| D0 (-) | RS485 B | RS485_NEG | RS485 B | TX- |
| 0V / Common | RS GND | GND | Not available | G |
ifm module
The configuration is handled physically on the IFM Module, not on the breaker's screen.
Use the two rotary dials on the front of the IFM module to set the Modbus address (1 to 99).
The IFM module automatically detects the baud rate and parity. However, ensure your Sofar EMS and the IFM are aligned.
Recommended settings for the IFM:
The driver performs a validation check upon connection. It verifies:
Troubleshooting If the driver fails to load, check the voltage readings on the MicroLogic X display. If the breaker sees 0V (is not connected to a live busbar) and is not powered by an external 24V supply, the communication might fail or be rejected by the driver's validation logic.
