PACIO MODULES
138 Parker Automation Controller Installation Guide
Module Control
The Module provides no operational options but a PROFIBUS-address, which is set by the EtherCAT-
master. The Module indicates errors by different "Module state" bits. These error bits are stored. To reset
the error bits, set control bit "ResetError" to a rising edge.
Variable Data type Explanation
SetOptions BOOL Rising edge

accepts the PROFIBUS address
ResetError BOOL Rising edge

acknowledges error
SPC3 Address
The PROFIBUS-DP-Slave address is set by the following variable. The assumption of the address is
released with the rising edge of SetOption. The execution is indicated with OptionSet. The PROFIBUS DP
slave address also can be changed at runtime.
Variable Data type Explanation
Address USINT PROFIBUS-DP-Slave address
Module State
The following Module states are indicated below. To reset the messages, see above.
Variable Data type Explanation

Module-Specific Messages
Apart from the Module error messages, there is a set of messages containing details about the current
state of the Module.
Variable Data type Explanation
ProfibusRunning BOOL PROFIBUS runs
Configuring the Data Modules
For the configuration of the EtherCAT and the PROFIBUS, the appropriate configuration files are needed.
These are:

ParkerEtherCATModules.xml for EtherCAT

Park6943.GSD for PROFIBUS
Number and size of the data Modules are configurable. The relationship of input data and output data is
always thereby 1:1. Select the desired data Modules in the respective Configurator tools.
