Connecting a CLICK PLC to MachineMetrics via Modbus TCP – MachineMetrics

This guide helps you connect a CLICK PLC with Modbus TCP/IP support to MachineMetrics for real-time machine monitoring. It includes compatible models, signal requirements, configuration instructions, and a sample MachineMetrics adapter script.

✅ Supported CLICK PLC Models

To connect to MachineMetrics, your CLICK PLC must support Ethernet communication using Modbus TCP/IP.

Known Compatible Models

CLICK Ethernet Basic CPUs
Examples:
- C0-10DRE-D
- C0-10DD1E-D
CLICK Ethernet Standard CPUs
Examples:
- C0-11DD2E-D
- C0-12DD1E-D

📌 Serial-only models do not support Modbus TCP and are not compatible.

📋 Minimum Required Signals

MachineMetrics requires the following signals to function properly:

Signal Name	Purpose	Format
Execution Status	Indicates if the machine is running or idle	Coil or Register
Part Count	Increments after each completed part	Coil or Register

These signals are used to drive analytics such as uptime, performance, and throughput.

🔍 How to Source Your Signals

To locate appropriate coils or registers in your CLICK PLC:

Open the CLICK Programming Suite.
Go to Data View or check the PLC Memory Map.
Identify:
- A coil or register that toggles ON while the machine is running.
- A register or counter that increments with each part cycle.
Record their Modbus addresses (e.g., Coil C1 = 00001, Register DS1 = 40001).
Confirm their behavior during machine operation or using simulation tools.

📤 What to Send to MachineMetrics

Please provide your MachineMetrics representative with:

✅ The PLC’s static IP address
✅ The Modbus TCP port (default is 502)
✅ The coil or register addresses for:
- Execution Status
- Part Count
❓ Optionally: any additional signals you'd like to monitor

🧪 Example Modbus Signal Table

Signal Name	Address	Type	Notes
Execution Status	`00001`	Coil	ON when machine is running
Part Count	`40001`	Register (int16)	Increments with each completed part

🧰 Sample MachineMetrics Adapter Script

Below is an example YAML script used in MachineMetrics to define the connection and data model for a CLICK PLC using Modbus TCP:

version: 2
unit-id: 1

coils:
  green-lamp:
   address: 1
  red-lamp:
   address: 2

 registers:
  counter:
   address: 40001
   type: int16

variables:
  execution:
   - source: green-lamp == 1
   - state:
    - ACTIVE: this
    - READY: true

 part-count:
  - source: counter
  - value-increase
  - count

data-items:
 - execution
 - part-count

📝 Key Notes:

unit-id typically stays at 1 for most CLICK PLC setups.
Coil and register addresses must match those configured in your PLC.
Execution is derived from a "green lamp" coil; part count is based on a register value.

🔧 PLC Configuration Tips

Set your PLC’s IP address to static.
Ensure Modbus TCP server is enabled in the communication settings.
Keep port 502 open between the PLC and the MachineMetrics Edge Device.
Confirm the edge device and PLC are on the same subnet or have routing in place.
