1) Device_type, Time_delay_short and Time_delay_long are
parameters that specify the response time of the station.
The parameter “Device_type” is used to determine whether it
is a fast (Device_type = 0) or slow (Device_type = 1)
responding station. “Time_delay_short” and
“Time_delay_long” are parameters that must be specified for
each station. If a station is assigned “Device_type” = 0, it will
respond with a delay time defined in “Time_delay_short”.
“Device_type” = 1 is assigned accordingly to
“Time_delay_long”.
If the PS416 is fast, it is only processing short frames with a
fast cycle time. A PS4-200 is always classified as a slow PLC.
After connection establishment, station A (e.g. PS416, fast)
will signal its “Device_type” = 1. In response, station B
(e.g. PS4-200, slow) will signal its “Device_type” = 0.
Station A will then respond to every frame from station B
with the delay time specified at “Time_delay_short”
(e.g. 300 ms), B will respond with a 600 ms delay.
The parameters “Time_rts_delay_off”, “Time_gap_time”
and “Time_cts_timeout” are only transferred at cold starts/
warm starts or when the module is reset.
tel_repeat 0 to 255 Number of frame repetitions in the event of a
protocol error
dial_repeat 0 to 255 Number of dial attempts if no connection can be
established due to the following error messages:
– NO CARRIER
– BUSY
– NO ANSWER
– BREAK
– RING DETECTED
If the “dial_repeat” input is set to “0”, the “alarm”
function block output is only triggered on error
code 2F.
