• Using PLC for Access Control

Currently we support 2 type of PLC.

• Wave-Share PLC

Enter you PLC URL Exmple:- 192.168.100.100:4196/1 

• 4196 - Device port can be changed to your requirment
• 1 - is the port number you want to use to for access

See Image for better understanding (Wave-Share)

• Barix Barionet PLC
