Hi,
you can use either COM3 port (PM85x or PM86x controller) or alternatively you can use CI853 module for Modbus over RS232 electrical standard.
at ACS880 side, there is RMBA-01 module for Modbus communication over RS485 electrical standard.
and of course a conversion device to convert RS232 to RS485 electrical standard.
Further, in PLC program, you can use MBConnect and MBRead function blocks to read the modbus register values from the drive.
And of course you need to know which Modbus register address has the required data.
Thank You.

You mean Control Builder v6.1?
All you need AC800M controller with CI853 card to communicate on Modbus RS232. Probably u may need RS232 to RS485 interface converter if ACS880 supports only RS485. And an application code with set of Modbus Connect and read blocks to read the relavant modbus registers from ACS880.
