System description
The field module IOLSHPB-P3104R01 has the following at each of the 5 pin M12 female
connectors ports 1 to Port 4:
one C/Q cable X(n), pin 4
one device supply L+/L-, pin 1/pin 3 and
one functional earth ground FE.
This assignment is also printed on the field module IOLSHPB-P3104R01.
Each port (1 bis 4) has four operating modes, which can be set individually using GSD
parameters.
In
digital input
mode, the binary state of the C/Q cable of the ports is displayed in the
process data.
In
SCAN
mode of a port, an attempt is made cyclically at approximately one-second
intervals to establish communication with an IO-Link device at each port. If communication
is established successfully, the C/Q cable state for this port switches to IO-Link mode and
remains in this state until communication is interrupted.
In
COM
mode, the IO-Link process data is displayed in the process data. When communi-
cation is aborted, e.g. “faulty cabel” or “M12 male connector not inserted”, an attempt is
made cyclically at approximately one-second intervals to establish communication.
In
digital output
mode, the port can be operated as a digital output.
In
SIO IN
mode with IO-Link access, an IOLD can be operated in standard input mode and
acyclic services can be exchanged without changing the operating mode. The SIO bit is not
valid during acyclic data exchange.
There are three different options for acyclic communication between the field module
IOLSHPB-P3104R01 and the IOLD:
1.
Indirect read/write access to the IOLD objects using the standardized IO-Link CALL
(DP/V1), which is implemented with PROFIBUS I&M functions (function block
available).
2.
Direct read/write access to the IOLD objects using DP/V1 (function block available).
3.
Direct read/write access to the IOLD objects using a configurable process data
channel via DP/V0.
