Hi - There are different ways you can do it. Below a simple way for Modbus RTU.
Solution with a Modbus Scanner at SCADAPack E Configurator
Ports - Configure your Port as Modbus Master(Modbus RTU), Mode RS485 2W and set the correct baud rate for your device.
Master/Modbus Scanner - Add a Device. Select the Device Type: Modbus Serial RTU, enter the Device Address, select the port that you configured and once you have that you can Add Points based on the Modbus registers of your device.
i.e. Operation:Read/Write, Modbus Data Type:INT, Modbus Register: Check the modbus registers for the device, DNP Point Type:Analog Output, DNP Point Number:20001(any number from 0-49999), DNP Point Qty:1(if they are consecutive single registers you can make up to 2000 points changing this).
Once you created the Device some points get created automatically. Go to your Analog Points and look for the one that says CommunicationStatus, if you read the point and get a 3 that means that there is no communication, a 4 is good comms.

Try to get the latest version of the E Configurator (8.14.6) because older versions had some issues with the modbus scanners.
I don't know if the ISaGRAF 3.5 support the E Series SCADAPacks. I suggest to move to the SCADApack Workbench 6.5. There is another way to read the Device I/O from the Workbench resource.
