There will always be a finite delay between the end of a message from the host (master) and the time at which the host is ready to receive the
response from the application module (slave). The application module does not respond until at least 1ms after the message has been received from
the host allowing 1ms for the host to change from transmit to receive mode. This delay can be extended using Pr x.08 if required for both ANSI and
Modbus protocols.
This parameter allows a delay to be configured between enabling the RS485 transmitter and commencing transmission of data.
Control where the output of the DPL Print command is sent. The following strings are defined:
The scheduling rate for the user program clock task in milliseconds. A value of zero disables the clock task.
