RS485

The RS485 interface is designed as a 9-pole
DSUB socket on the EM-PQ2500.
On this interface, the EM-PQ2500 supports the
following selection of protocols:

•

Modbus RTU

•

Profibus DP V0 Slave

For connection, we recommend a 9-pole Pro-
fibus plug, e.g. from the company Phoenix,
type "SUBCON-Plus-ProfiB/AX/SC“ with article
number 2744380.

Illu. EM-PQ2500 with DSUB socket for the
RS485 interface.

DSUB socket

for Modbus
or Profibus.
