4.5.2 PGU connection (PORT # 0, PCD1 and PCD2) (RS-232)
as communication interface
When comissioning / programming are complete, the port can be used for other pur
-
poses.
Option 1:
Configuration with desired protocol
(S-Bus PGU configuration)
Option 2:
Assignment (SASI) in the user program
(the port must not be configured as an S-Bus PGU port)
■ If another programming device is connected during operation
instead of the peripheral device, the unit will switch over
automatically to PGU mode (pin 6 logical “1” (DSR); in PGU
mode: DSR PING = “1”).
■ Before using the port to connect another peripheral device,
Port #0 must be reconfigured by means of an SASI instruction.

1) When communicating with terminals, check whether some connections are pro-
vided with bridges or need to be set to “H” or “L” with the “SOCL” instruction. It is
generally recommended to use a handshake (RTS / CTS)
