4.6.2 TM-C parameters
Selection of channel activation
Enables channel activation. The counter channel is always activated since there is only a
single channel.
Selection of operating type: Counting/Position input
Enables whether to provide integer counter value. This selection is always enabled for the
counter module and a counter value is always returned.
Selection of operating type: Measuring
Enables whether to provide an additional counter measured value. This selection is always
enabled for the counter module and a measured value is always returned.
Signal monitoring
Allows you to enable or disable signal monitoring. Signal monitoring evaluates the quality of
A and B signals for phase, voltage, and wire break. If signal monitoring is disabled, you must
evaluate and provide safety measures suitable for your application. See "A and B signal
monitoring" in "Counter input diagnostics (Page 20)" for the effects on safety and the
precautions you must make if you disable signal monitoring.
It is possible for a channel fault to occur that is not readily detected by the module
diagnostics if signal monitoring is disabled.
Disabling this feature reduces the safety rating to SIL 1, Cat. 2, PL c, which causes a loss of
the safety function. Disabling this feature can result in unexpected machine or process
operation, which can cause death, severe personal injury, and/or property damage.
If signal monitoring is disabled, A and B signal or wire break errors detected are not reported
and you might not achieve your required level of safety. You must provide your own safety
measures if you disable these features.
Signal Type
Specifies whether the encoder is providing A, B, or A, B, N signals. If (A, B) is selected, then
Pulses per revolution and Reaction to N signal are disabled.
Invert direction
Specifies whether to reverse the counting direction.
