Parameter
Description
Channels CH0 - CH7
Input delay
Selects the input delay for the signal at the respective channel
for suppressing interferences. Changes to the signal are only
detected if they remain stable for longer than the configured
time.
Bus terminating resistor
Activates the internal terminating resistor of the RS485 input
channel. Only works under the following conditions:
• The RS485_bidir or RS422_input is set for the
RS485_OR_TTL_DIRECTION system logic parameter of the
channel.
• For the RS485_TERMINATION system logic parameter of the
channel, parameterized is set.
Bus termination resistors can be used only for CH0, CH1 and
CH4 channels.
You can find additional information about the system logic parameters in the programming
manual Creating a TM FAST Application
