H8250
Error message
Safety comm. Received error info
Cause
Error information was received from the master station with which the safety
communication function (CC-Link IE TSN) is communicating.
Solution
Check the master station error.
H8252
Error message
Safety comm. timeout
Cause
A timeout error occurred in the safety communication function (CC-Link IE TSN).
Solution
・
Check that the parameter
“
safety refresh monitoring time
”
set on the master
station is an appropriate value.
・ Check if measures against noise in the transmission path are taken and wiring
and devices have no problems.
・ Check that no online operation is being performed from a peripheral such as the
engineering tool, or no program or parameter is being written to the master station.
・ If the same error occurs again, the possible cause is a hardware failure. Contact
the manufacturer.
H8253
Error message
Safety comm. timeout
Cause
A timeout error (unacceptable delay) has occurred in the safety communication
function (CC-Link IE TSN).
Solution
・
Check that the parameter
“
safety refresh monitoring time
”
set on the master
station is an appropriate value.
・ Check that the parameter “transmission interval monitoring time” set on the
robot controller is an appropriate value.
・ Check if measures against noise in the transmission path are taken and wiring
and devices have no problems.
・ Check that no online operation is being performed from a peripheral such as the
engineering tool, or no program or parameter is being written to the master station.
・ If the same error occurs again, the possible cause is a hardware failure. Contact
the manufacturer.
H8254
Error message
Safety comm. timeout
Cause
A transmission interval error (communication destination) of the safety
communication function (CC-Link IE TSN) has occurred.
Solution
・
Check that the parameter
“
transmission interval monitoring time
”
set on the
master station (communication destination) is an appropriate value.
・ Check if measures against noise in the transmission path are taken and wiring
and devices have no problems.
・ Check that no online operation is being performed from a peripheral such as the
engineering tool, or no program or parameter is being written to the master station.
・ If the same error occurs again, the possible cause is a hardware failure. Contact
the manufacturer.
H8257
Error message
Safety comm. data error
Cause
A data error has occurred in the safety communication function (CC-Link IE TSN).
Solution
If the same error occurs again, the possible cause is a hardware failure. Contact
the manufacturer.
