Now, you can link up to 10 process data words to the PLC program or write data into
them for manual testing as shown in the following figure.
First, mark the process output data PO1. In the window that appears, choose the tab
page "Online". Click on the "Write" button. The "Set Value Dialog" window opens. Enter
your data in the field "Dec" or "Hex". Handle the PO2 process output data in the same
way.
The 10 process input and output data words are assigned and scaled in MOVIDRIVE
®
B in the 87_ parameter group or defined via an IPOS
plus®
program or application mod-
ule.
For more information, refer to the "MOVIDRIVE
®
MDX60B/61B communication and
fieldbus unit profile" manual.
6.1.2 EtherCAT
®
timeout (MOVIDRIVE
®
MDX61B)
If data transfer via EtherCAT
®
is disturbed or interrupted, the response monitoring time
(standard value 100 ms) configured in the master elapses in MOVIDRIVE
®
MDX61B.
The DFE24B "ERR" LED signals that no new user data can be received. At the same
time, MOVIDRIVE
®
MDX61B performs the fault response selected with P831 Fieldbus
timeout response.
P819 Fieldbus timeout displays the response monitoring time specified by the master
during the EtherCAT
®
startup. The length of the timeout can only be changed via the
master. Although modifications made using the keypad or MOVITOOLS
®
are displayed,
they do not have any effect and are overwritten during the next startup process.
6.1.3 Fieldbus timeout response (MOVIDRIVE
®
MDX61B)
Parameter P831 Response Fieldbus Timeout is used to set the fault response that is
triggered via the fieldbus timeout monitoring function. The parameters set here should
match the configuration of the master system.
