CANopen and IQAN GFOUT/GFIN identifier

What is the Gfout identifier value?
Background: Have used the norgren vs18 canopen pneumatic valve for years. Identifier was 200hex+nodeid.
Have to switch to the metalwork Eb80 pneumatic valve. Metalwork provide a EDS configuration file which is not supported by iqan. How do you find the direct canopen identifier to use?

Here is the manual and EDS file...
EB80 CANOPEN manual
I took the liberty to edit the title of the question.
To give a very brief explanation, the CANopen COB-ID is what you enter as Identifier on the Generic CAN channels GFIN/GFOUT in IQANdesign.
In the IQANdesign solutions library, you can find an example of how a math channel is used for calculating the COB-ID.
This example is for a Tramit PDO (sent by the sensor)
For most CANopen nodes, the COB-ID follow the defaults, where the COB-ID of the first recieve PDO is 0x200+Node ID, and the COB-ID of the first transmit is 0x180 + Node ID.
You find the COB-ID for the messages you will use in the EDS file, but if you read one for the first time it can be overwhelming.
If you for example look at the EDS for a Parker Moduflex, you'll find this entry
ParameterName=Receive PDO Communication Parameter
ParameterName=Number of Entries
