5.4 Configuring the Registers to be Exchanged in Cyclic Communication

In the start up routine for Profibus communication the card firstly enters parameterisation mode and
adjusts the card parameters according to the GSD file settings. Next the card enters configuration
mode where the configuration settings in the GSD file are used to determine the registers to be
exchanged with the PLC during the normal cyclic messaging.
The configuration stage allows for the tailoring of the registers to be exchanged to allow the system to
be tuned to improve data throughput. If certain information or controls are not required by the PLC
then they may be left out of data exchange by choosing the appropriate configuration.
Both the PLC and the card must be aware of the configuration chosen for successful data exchange.
The Profibus DP Module (Mk2) has 10 possible configurations as indicated in the table. The default
value is Configuration 1. The PLC must send a Check Configuration message during start up to
confirm the Configuration to be used.

The current value of the analogue input is reported as an Integer
Value in the range 0 to 1000 (0 – 3E8 hex) representing the
percentage value to 0.1% resolution.
The input may be 0 to 5V or 0 to 20mA d.c. from an externally
powered field transmitter (the actuator does not provide the power for
the transmitter).
The input must be calibrated during the set up of the PFU using the
Analogue Input Max parameter. Apply a 100% signal and write a
value to the parameter, the current value will then be reported as
100%. The scaling is retained in EEPROM when the actuator power is
removed.
reported as an integer in the range 1 to 10 (1-A hex).
