The HC-232-SIG-Z7 makes your PLCs smart in an easy like a Sunday morning fashion. This device can read any data frame coming from a PLC of up to 100 bytes at variable speed, sending to the cloud up to 12 bytes containing your data points of interest.

As an example of metrics, it can gather and communicate data such as manufactured unit number ‘10’ of a total of ‘68’ units of product ‘B’ to be manufactured, being produced in line number ‘5’ with the required input ‘WZ0045’. This information is sent by the PLC through RS232 or Ethernet connection. 

Another example of potential applications is the optimization of weight control scales in fields like food production. Every time a scale performs a measurement, the device registers and sends ‘weight’, ‘time’ and ‘product ID’ data points. Thus, production line workers do not have to do this process manually, eliminating potential errors, negligent behavior and inaccurate reporting in general.

Similarly,this solution can read a broad variety of sensors connected to a given PLC. Temperature, humidity, pressure, flow, levels, gas concentration, you name it, all with the high standards in secure data transmission that Sigfox connectivity is well known for.
