A basic point-to-point serial interface for integrating established field devices with S7-1500.
Siemens 6ES7540-1AB00-0AA0 is a SIMATIC S7-1500 CM PtP RS422/485 BA communication module for serial device integration. It provides a 15-pin D-sub interface and supports Freeport, 3964(R) and USS communication at rates up to 19.2 kbit/s. The module is useful when an S7-1500 controller must exchange data with established instruments, drives or devices that use RS422 or RS485 links. For a replacement project, compare the complete order number, protocol, interface mode, pin assignment, cable length and the configured communication parameters with the installed hardware and program.
