Groov view as a web server, and pac in Epic as a Core Controller.
In EPIC, I Create Tags Read from such as OPC UA, Modbus Devices, Pac in EPIC…, My question is how could I pass these Tags to Pac in Epic to Code.

If you need to pass data from one device to another, you would want to use Ignition Edge for this. You can find information on how to do this in this forum post. .
Ignition Edge Licence in EPIC limited 2 hrs, is this the only way to share Tags in the same EPIC (Between EPIC groov view and EPIC PAC) ?
For sharing PAC Control tags to groov View, just add an ‘Opto 22 Controller’ device.
But your post title mentions Siemens Device. For Siemens, you will need to use the Ignition Edge module to talk to that PLC.
If you are moving the tags from Siemens via ModbusTCP then you can go directly from the Modbus device to groov View by adding a ModbusTCP device, or use the Modbus PAC Control toolkit.
“If you are moving the tags from Siemens via ModbusTCP then you can go directly from the Modbus device to groov View by adding a ModbusTCP device, or use the Modbus PAC Control toolkit.”
Yes, I did that as you described.
The scenario is: I have already obtained Siemens PLC variable TAG via MODBUS DEVICE in EPIC GROOV, and I want to share the use of variable TAG from EPIC GrooV in EPIC PAC.
There are several ways to do this:
1 Use ignition, Licence charge, not considered for now a small project.
2 Read Siemens PLC directly via MODBUS TCP in EPIC PAC, it has nothing to do with EPIC GrooV, or it can’t be realized that EPIC PAC and EPIC GrooV can share the variables, unless ignition is used?
3 If I have a gateway unit configured with a MQTT server, can I use the gateway MQTT server to enable the EPIC PAC to read/write the EPIC GROOV variable TAG?
So we are on the same page, lets set some terms.
EPIC is the controller
groov View is the HMI (graphics interface)
groov Manage is the menu system on EPIC controller
PAC Control is the strategy engine running the charts.
Once tags are in groov View, you can not share them with anything else.
Since you are bringing the Siemens tags into groov View via ModbusTCP and you want them in PAC Control (for some reason) and you don’t want to pay for Ignition, then you will need to change from getting the ModbusTCP tags in groov View to getting the ModbusTCP tags into PAC Control.
That way you will have the Siemens data in PAC Control and from their you can put them in grooov View and use them in other places.
Since you know the Siemens IP address, port number and register addresses,
Down load the toolkit. Read the guide and move the Siemens data into it.
