1. Introduction to PLC1.1 Understanding PLC Hardware
PLC Mode• RUN: SCAN Cycle starts and Ladder Logic starts processing• STOP: SCAN Cycle stops and Ladder Logic does not work and all
the (non retentive) memory bits gets reset
COM1 USB Programming Port• Requires USB Cable to program the PLC
COM2 and COM3 – Rs 485 Communication• To link external devices for PLC
communication. Example HMI, VFD etc.
Ethernet Interface
• To link the PLC with Ethernet devices like HMI, Servo etc. or to link it to network for SCADA interface.
• Standard Ethernet cable can be used for interfacing
PLC Inputs• 8 Digital Inputs: X0 ~ X7 (Octal number system)• Maximum 256 Outputs• Can be configured for PNP or NPN Wiring

1. Introduction to PLC1.2 How to Link PLC and PC
Step 2 – Find PLC in COMMGR
If you are using router, just plug it to the available Ethernet port. In the router make sure DHCP mode is available.
Open COMMGR, select Connection type Ethernet, select Ethernet card and click search
Step 3 – Click OK and make sure the status of this connection is ‘Start’
