If the function block input type is set to Dual Channel Equivalent (2 Pairs) or
Dual Channel Complementary (2 Pairs) for the Safety Gate Monitoring func-
tion block, the synchronization time (i.e., the time between changes in the
input pairs) can be evaluated.
The time between when one of the input pairs changes until the other one
changes is monitored. If the second input pair does not change before the
synchronization time expires, an error will occur and the Output Enable output
from the function block will not turn ON. The time between changes in the
input pairs will not be monitored if the synchronization time is set to 0.
Function tests are supported when using the Safety Gate Monitoring function
block.
If the function test is enabled when the NE1A-series Controller is started, a
safety gate test must be performed when the function test request signal is
input from the machine.
The number of inputs and outputs for logic functions can be increased.
Optional outputs from function blocks can be enabled.
