● Send delay time (after CTS)
The delay time (ms) is used when readiness to send (CTS signal) is received from the
modem and when 0 (null) has been configured for the "RTS/CTS delay time".
–
Value = 0
Transmission is not delayed until the CTS signal of the modem.
– Value > 0
As soon as the CTS signal is received from the modem, the send delay time is started.
Sending starts after the time has elapsed.
Default setting: 0. Permitted range: 0...65535 ms
● RTS off delay
Only configurable with: TIM 1531 IRC
The RTS OFF delay (ms) defines when the module takes back the RTS signal after
sending.
–
Value = 0
The module takes the RTS signal back immediately after sending the last character.
– Value > 0
Once the last character has been sent, the RTS OFF delay elapses before the module
takes back the RTS signal.
Default setting: 0. Permitted range: 0...65535 ms
● Polling monitoring time
Only configurable with: TIM 3V-IE DNP3 / TIM 4R-IE DNP3
Only for interfaces with the Network node type "Station" / "Node station".
Time (s) after which the TIM expects to be polled. After this time elapses, the TIM sends
a message to its local CPU indicating that the master station is disrupted.
Default setting: 30. Permitted range: 0...65535 s
–
Parameters configured:
After the configured time elapses, the module sends a message to its local CPU.
– Parameter not configured at a transmission speed of 9600 bps:
After 4 seconds without frame traffic, the module outputs a message.
– Parameter not configured at a transmission speed of 1200 bps:
