Response delay in ms in RS485 Mode
000 = no delay
1 = in the event of a fault, an error message is sent automatically via the
interface (RS 232 only).
0 = function disabled
Station number 01 - 32
Interface confirmation (Y CR LF)
0 = off
1 = on
Handshake / Checksum:
0 = checksum validation on
- hardware handshake RTS/CTS off
1 = checksum validation off - hardware handshake RTS/CTS off
2 = checksum validation on - hardware handshake RTS/CTS on
3 = checksum validation off - hardware handshake RTS/CTS on
Explanation of the term ‘Response Delay’:
In RS485 Mode, once the CLM receives the last character of an 'LF'
request (Linefeed: ASCII Code 10), it immediately switches over to Send
Mode. With various RS-485 PC driver cards, this leads to problems if the
cards are unable switch to Receive Mode quickly enough.
The interface can delay the switch from Receive to Send Mode by a
defined amount of time (response delay).
The PC driver should be able to switch reliably from Send to Receive
Mode within this time limit. The response delay is rounded up to whole
number multiples of the controller cycle time (see Parameter B010).
