Can the Altivar Drivecom programming block on a Twido PLC be used to control an ATV58 through Modbus?



No. The ATV58 cannot be controlled by a Drivecom programming block with a Twido PLC. There are only two Drivecom programming blocks for controlling the ATV31 and the ATV71.
Instead of using Drivecom, use XMIT or similar serial communications register block to control the drive using command words.
