ALR111-S00 Serial Communication Module Yokogawa 

Hardware Specifications

Yokogawa DCS Serial Communication Interface Characteristics

The ALR111-S00 module performs RS-232C serial communication between the Yokogawa FCS and external subsystems such as FA-M3 equipment. Moreover, it uses start-stop synchronization to manage asynchronous data transfer with configurable character length, stop bits, and parity settings.

The module supports ASCII and binary transmission formats. Therefore, users can configure communication parameters according to subsystem requirements. In addition, the half-duplex communication mode controls the transmit and receive operation through a single serial interface path.

The module is installed in Yokogawa FIO field control hardware, including AFV30, AFV40, AFV10, AFF50 field control units, ANB10 ESB bus node units, ANB11 optical ESB bus node units, and ANR10 ER bus node units.

Frequently Asked Questions

Q: What serial interface does the Yokogawa ALR111-S00 provide?
A: The ALR111-S00 provides two RS-232C serial communication ports for point-to-point subsystem communication.

Q: What communication parameters can be configured on the ALR111-S00?
A: The module supports transmission speeds from 1200 to 38400 bps, 7 or 8 bit character length, 1 or 2 stop bits, and none, even, or odd parity checking.

Q: Can the ALR111-S00 operate with Yokogawa FIO hardware nodes?
A: Yes. The module mounts on supported Yokogawa FIO hardware units, including ANB10, ANR10, AFF50, AFV10, AFV30, and AFV40 platforms.

Field Installation Guidelines

Install the ALR111-S00 module in the designated Yokogawa FIO mounting locations and verify the module seating position before system startup.

Use the specified Yokogawa communication cables for RS-232C wiring. Keep serial signal cables separated from high-voltage power cables and strong electromagnetic interference sources.

Ensure proper cable shielding practices during field installation. Connect shield layers according to the system grounding design to reduce electrical noise during serial data transmission.

Confirm communication settings between the ALR111-S00 and connected subsystem devices before enabling data exchange. Verify baud rate, parity, character length, and stop bit configuration on both communication ends.
