01
Two configurable channelsConfigure each port independently as RS232 or RS485 and document the matching cable, grounding, termination and serial parameters.
02
Programmable application protocolABB lists programmable communication with Modbus and ASCII as examples; the application logic must implement the required frame handling.
03
Included field connectorsTwo 9-pin TA532 spring terminal blocks are delivered with the communication module. The separately listed TA532 pack is a spare-parts package.
04
CPU-side moduleCM574-RS exchanges data with the AC500 CPU through dual-port memory and mounts on a compatible TB5xx terminal base.
02

Protocol Engineering & Serial Wiring Checks

A safe migration or replacement requires the old port settings, cable pinout, protocol timing and PLC application to be captured before hardware is removed.

Application checkpoints
01
RS232 point-to-pointSelect EIA RS232 for the corresponding point-to-point electrical interface and match signal direction, reference and cable length.
02
RS485 multidropSelect EIA RS485 for the specified two-wire serial network and apply the required polarity, termination, biasing and shield practice.
03
Modbus RTU projectsUse the Automation Builder application and serial parameters required by the connected Modbus devices.
Conversion checkpoints
01
ASCII integrationsProgrammable ASCII communication can support proprietary equipment, but the PLC program must define the message framing and data handling.
02
Spare terminal blocksTA532 order code 1SAP182000R0001 is listed as a 10-piece spare set, not as another communication module.
03
XC environmental optionCM574-RS-XC provides the corresponding extreme-condition construction; confirm the full environmental specification rather than substituting by appearance.

Buyer Questions for ABB CM574-RS

Port standards, programmable protocols, terminals, migration and ordering checks.

01 Can each serial port on ABB CM574-RS be configured separately as RS232 or RS485?
Yes. ABB specifies two software-configurable serial interfaces. Record the electrical standard, baud rate, data bits, parity, stop bits and cable pinout for each channel.
02 Which communication protocols can ABB CM574-RS run?
ABB describes the protocol as programmable in Automation Builder and lists Modbus and ASCII as examples. The PLC application must contain the required protocol handling and serial settings.
03 Are the two TA532 terminal blocks included with ABB CM574-RS?
Yes. ABB states that the dual-serial module is delivered with two 9-pin TA532 spring terminal blocks. The separately ordered 1SAP182000R0001 item is a 10-piece spare set.
04 Can ABB CM574-RS replace ABB CM574-RCOM without engineering changes?
No. The products serve different communication functions. Compare protocol, electrical interface, application program, field wiring and connected equipment before selecting any replacement.
05 What must be backed up before changing an installed ABB CM574-RS?
Back up the AC500 project and both port configurations, then record the terminal pinout, cable shields, network termination, device addresses and communication timing.
06 What information is required for an ABB CM574-RS quotation?
Provide order code 1SAP170400R0201, nameplate photos, CPU and terminal base, RS232/RS485 selection for each port, protocol, quantity, destination and delivery date.

Transaction Cases

Sincere Cooperation, Long-Term Trust

Three customer journeys showing careful verification, clear communication and repeat cooperation.

Russia 01
A Russian customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.
India 02
An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.
Venezuela 03
A Venezuelan customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
