13.15 Serial interface

Each serial interface (Com1, Com2) can be executed with two different interface cards in the
multifunction panel (optional, see order details). One RS232 interface and one RS422/485 in-
terface are available. The type of interface card used is automatically identified by the multi-
function panel (hardware ID).
 Chapter 1.4 "Identifying the device version", page 16
Both serial interfaces can be operated as a master or slave with the Modbus protocol (Modbus
RTU).
For more information on using the serial interface with the Modbus protocol, see:
 Chapter 14.4 "Modbus frames for reading", page 212
 Chapter 14.5 "Modbus frames for writing", page 213
For more information on using the serial interface with a barcode scanner, see:
 Chapter 7.8.2 "Batch control via barcode scanner", page 71
 Chapter 16.3 "Barcode", page 269
Communication via Modbus is described in more detail in the separate Modbus interface de-
scription (B 705060.2.0).
