Product Description
The PSS/ACM12 from Yokogawa is a high-reliability serial communication module designed to meet the demands of complex industrial networking environments. Supporting RS-422 and RS-485 communication standards, this module facilitates both point-to-point and multipoint data transmission, making it a critical component for distributed control networks. With the ability to transmit data over distances of up to 1200 meters, the PSS/ACM12 ensures consistent and reliable communication, making it ideal for process automation and monitoring tasks.
This module is highly flexible, offering configurable parameters such as baud rates, parity settings, and character length, ensuring precise control for complex synchronization in industrial processes.

Compatibility and Installation Notes
The PSS/ACM12 is designed to integrate within a dedicated communication module nest. It is not compatible with the ACF11 unit, but can be combined with the ACM11 unit for extended functionality. To ensure stable communication over long distances, always use shielded cabling. For interfacing with the FA500 system, use the AKB161 cable for optimal performance, particularly for distances up to 100 meters.
When configuring this module, ensure that the signal reception timing (1 ms) is correctly implemented within your software logic to prevent data collisions during half-duplex communication.
Frequently Asked Questions
What is the maximum communication distance for this module?
The PSS/ACM12 supports a maximum total cable length of 1200 meters, provided shielded cabling is used to minimize interference and maintain signal integrity.
Can I use this module with the ACF11?
No, the PSS/ACM12 is incompatible with the ACF11 module. However, it can be combined with the ACM11 unit within the appropriate nest configuration.
Why can I not specify "no parity" at 19200 bps?
This is due to a technical limitation in the module's internal clock synchronization. When operating at the highest baud rate of 19200 bps, parity must be set to either Odd or Even to ensure stable data framing, as no parity is unsupported at this speed.
