Setup the GRT1-PRT Configuration
Section 3-3
Note
A failure of the GRT1-PRT during I/O data exchange will always be reported
to the CS1/CJ1 PLC CPU. If Auto-CLEAR has been enabled, the failure to
respond will result in the PROFIBUS Master Unit switching to CLEAR mode.
Diagnostics Update Delay
The Diagnostics Update Delay defines the number of PROFIBUS DP cycles
during which the PROFIBUS Master Unit will ignore diagnostics message
returned from the GRT1-PRT containing the Prm_Req flag. During the Diag-
nostics Update Delay period the PROFIBUS Master Unit will continue
requesting its diagnostics data.
I/O Module Tab
The I/O Module Tab, shown below, defines the I/O Configuration for the
GRT1-PRT. This I/O Configuration is downloaded to the PROFIBUS Master
Unit and sent to the physical device by the Master Unit for verification at the
start of communication.
Selecting the I/O
Configuration
The I/O Configuration can be selected using the following procedure.
1,2,3...
1.
Select the first row and double-click it using the left mouse button. A drop-
down list will appear (see figure below).
2.
From the drop-down list select the type of slice which is in this first slot,
right next to the GRT1-PRT.
3.
Select the next slot and repeat steps 1 and 2.
Control
Description
Continue if slave not
responding
The PROFIBUS Master Unit will continue to send I/O data
exchange messages, when the GRT1-PRT device fails to
respond. The diagnostics data of the GRT1-PRT will not
be updated.
Abort if slave not
responding
The PROFIBUS Master Unit will abort the data exchange
with the GRT1-PRT Unit, and continue to send diagnos-
tics request messages to the GRT1-PRT, until it responds.
The diagnostics data of the GRT1-PRT will be updated
accordingly.
