In every industrial set-up there is always a requirement of sending the status of a few digital inputs from one place to other for monitoring or interlocking purposes. Normally this is realized through standard Inputs and outputs of any PLC system either wired or through a communication network. But in some cases it is also required to monitor inputs at moving machines (either from static location to moving machine or vice versa or from one machine to other.
Wireless Master and Slave Modules (WMM & WSM)
This system monitors 4 digital input signals from a remote location using wireless communication and makes those signals available as 4 digital outputs at Master Module end and to PLC over Modbus TCP/IP, simultaneously. The system can also be used in different configurations to send and receive data using multiple Masters and Slaves.
