06 Jun 2025

Overview

Crimson 3.2 includes Ethernet and Serial Modbus drivers that easily connect to Red Lion PM-50 Meters. These drivers provide access to all PM-50 registers. The drivers contain all register information. Further, the drivers include the facility to automatically create Crimson data tags mapped to PM-50 variables, allowing the rapid creation of complex applications without the need to manually create and map data tags. Finally, the default communication setting in this driver match the defaults in the PM-50.

Use Case

The Crimson 3.2 drivers include the facility to automatically create Crimson data tags mapped to PM-50 variables, allowing the rapid creation of complex applications without the need to manually create and map data tags.

 

Required Software

Crimson 3.2

 

Ethernet Driver

The PM-50 Ethernet driver exchanges data between a PM-50 and FlexEdge using Modbus framing on the PM-50 WIFI or wired Ethernet.

 

Port Configuration

After selecting this driver, all port parameters match the PM-50 defaults. If the PM-50 defaults are changed, change the corresponding driver parameter.

 

Target Device Configuration


The PM50 Model and IP Address must be selected. All other parameters match the PM-50 defaults. If the PM-50 defaults are changed, change the corresponding driver parameter.

Target Device Parameters

  • The PM50 Model parameter selects a set of registers. Select PM500A or PM500D based on the part number of the PM-50 Meter.
  • The IP Address parameter sets the IP Address of the target device.

 

Serial Driver

The Serial driver uses Modbus framing.

 

Port Configuration

After selecting this driver, all parameters match the PM-50 defaults. If the PM-50 defaults are changed, change the corresponding driver parameter.

 

Hint

After you get the Serial Driver working with the PM-50, change the Protocol Type to Modbus RTU in this driver and in the PM-50 to get better performance.
