Wireless 4 digital input module - MIDAM WIN401
Wireless, battery operated module featuring four digital inputs. Native modbus map grants seamless integration into any SCADA systems. The communication is based on the AES128 encrypted Midam KFP protocol, which allows to update the device firmware on a wireless basis.
- Battery-powered operation
- 4 digital inputs
- Native Modbus map
- Wireless transmission
- Integration into SCADA systems
Function
The WIN401 module monitors up to 4 digital inputs. The signal is sent to a receiver, such as a wireless DALI converter (WDALI01, WDALI51), wireless digital outputs (WOUT251, WOUT261), or a wireless gateway (WCOM01 or WCOM51). Wireless communication is based on an unlicensed 868 MHz band. Embedded AES 128-bit, provides the most secure encryption standard for wireless connections. All digital inputs are configurable and four buttons or combinations can be used. Inputs 3 and 4 can be configured to use the status function (rocker switch monitoring) and inputs 1 and 2 to use the push button function. The device has factory-set values to ensure the correct default function and allows direct reading and writing of values to the Modbus map, which is available in a separate document. All settings are also stored in the Modbus map directly in the device. Before using the device for the first time, it is necessary to pair it and it is recommended to perform individual configuration, especially to change the encryption password.
Application
- Battery-powered operation
- 4 digital inputs
- Native Modbus map
- Wireless transmission
- Integration into SCADA systems
Pairing
Two devices are required for mutual communication. Both must be powered and located in close proximity to each other. Usually, wireless gateway or configuration dongle is used to set up remote wireless devices. Use look-up function in software tool to display a list of all available devices in range and assign or adjust parameters based on wireless ID code for each single device. There is a comprehensive help section integrated in the software tool to provide support during the wireless device set up procedure.
SCADA system integration
The module can be integrated through the fan coil controller WFC01001, via the Modbus RTU (RS485). For direct integration of the device, use of wireless gateways, such as WCOM01, or WCOM51 is recommended.
Midam KFP Password change
Prior to the first use, the encryption password (default “MIKROKLIMA1234AB”) must be changed using the WUSB01 configuration dongle and the relevant software tool.
