Fernhill SCADA Idec Micro Tags

The Idec Micro driver provides these tag types to support communication with Idec Micro PLC Devices:

IconTag TypeVersionDescription
Channel IconIdec Micro serial channel2.1A serial port used for Idec Micro serial communications.
PLC TagIdec Micro PLC Tag2.1An Idec Micro PLC Tag.
Register Block TagIdec Micro Register Block Tag2.1A block of registers read from an Idec Micro PLC.

To configure Fernhill SCADA to communicate with an Idec Micro PLC do the following:

  1. Create and configure a Idec Micro Serial Channel Tag.
  2. Create a Idec Micro PLC Tag. Set the Channel property of the Idec Micro PLC Tag to the channel tag you created in step 1.
  3. Create I/O Data Point Tags to represent the data in the Idec Micro PLC. For each I/O Data Point Tag you create:

Fernhill SCADA I/O Data Point Tags

You can use these I/O Data Point Tags to represent individual data points in the PLC:

Autodetect Wizard

The Idec Micro Serial Autodetect Wizard searches serial ports for Idec Micro PLC Devices. The Wizard tries different combinations of parameters to try and find PLC Devices. If a PLC is found, the wizard will automatically create the correct configuration to communicate with the PLC.
