Intelligent Actuator (IAI) RCON Data Mapping to Mitsubishi CC-Link or CC-Link IE Field


Question

Posted

How exactly does the mapping work on CC-Link or CC-Link IE Field for an RCON Gateway and actuators?

First start by running the Gateway Parameter Configuration Tool to set up the RCON's Gateway

Select RCON

Go to File->New File, Then pick the network

Depending on whether it's CC-Link or CC-Link IE Field you will have slightly different options for Network Number, Node Address, and Baud Rate.  Set those as necessary.  But on the right you'll have the following:
Axis Type - this is the number of CON type axes in your system (RCP, RCS, etc)
Number of Option Units - this is the number of EC type slices you have on your RCON
Then there's the drop down for operation mode of the CON type axes.  When you want the most control set this to "Direct Indication (Size 8W).  That means 8 words out and 8 words in from each axis for control an monitoring.  

You can set each axis separately if needed, but typically we recommend 8W mode for all CON axes.

At the bottom then (shown in red) will tell you the size of the CC-Link data black - this has to match your PLC's configuration for the CC-Link or CC-Link IE Field network for this device.

Then we have to be able to map the data into the PLC's memory.  From IAI's documentation, the Gateway itself has a data structure:

For CC-Link networks you'll then see that the Gateway Control 2 words (32 bits) get mapped into RY bits

And the Gateway Status bits get mapped into RX

The details of each bit are here:

Then filling out further RX and RY devices are more gateway status and control data.  There's no more control bits used in RY, but there are full words for power supply status etc in further RX addresses

Now assuming you chose 8W control for your CON axes each axis has this data structure of 8 words in and 8 words out

These will map to RWr and RWw addresses.  So if you have say 4 axes you will get:

Then if we add EC axis to the end, each EC slice does 4 axes and takes up one word in and one word out for these 4 axis.

This will be at the end of the other data in the RWr and RWw after the CON axes and looks like this

Hopefully this helps you determine your addressing for RCON gateways.
