A1: It supports Modbus RTU and Yokogawa proprietary protocols over RS-422 and RS-485 interfaces.
Q2: Can the ACM22 operate in both half-duplex and full-duplex modes?
A2: Yes, configuration allows operation in either mode depending on network setup.
Q3: Is electrical isolation provided between communication ports and the system bus?
A3: Yes, both optical and galvanic isolation are implemented to prevent interference.
Q4: What is the maximum RS-485 communication distance?
A4: Up to 100 meters using shielded twisted-pair cables.
Q5: Can the ACM22 communicate with third-party PLCs?
A5: Yes, as long as the PLC supports Modbus RTU or RS-485 standards.
Q6: What baud rates are supported?
A6: 300 bps to 115.2 kbps, configurable via engineering software.
Q7: Is there any special configuration required for multi-drop RS-485 lines?
