7 ZNA (x 20 ms) Time after request (ZNA)
Waiting time to be complied with until the next transmit
request is executed.
The ZNA is given as a factor of 20 ms steps.
0 ... 255 [ms] (0x00 ... 0xFA)
0x00
Option 3, character delay time (x 20 ms)
8 Character delay time
(x 20 ms)
Character delay time; the character delay time defines the
max. permissible interval between two received characters
within a frame.
The character delay time is given as a factor of 20ms steps.
If the character delay time is 0, the module independently
calculates the character delay time on the basis of the baud
rate (approx. the double character time).
0 ... 255 [ms] (0x00 ... 0xFA)
0x00
Option 4, acknowledgement time (x 20 ms)
9 Acknowledgement
time (x 20 ms)
The acknowledgement time defines the max. permissible
interval until the partner is acknowledged while
establishing/terminating a connection.
The acknowledgement time is given as a factor of 20ms
steps.
1 ... 255 (0x01 ... 0xFF)
0x00
Option 5, block wait time (x 20 ms)
10 Block wait time (x 20
ms)
The block wait time is the maximum time period between
confirming a request frame (DLE) and STX of the response
frame.
The block wait time is given as a factor of 20ms steps.
1 ... 255 (0x01 ... 0xFF)
0xFA
Option 6, STX repititons
11 STX repetitions Maximum number of times the module attempts to
establish a connection.
1 ... 255 (0x01 ... 0xFF)
0x01
Option 7, DBL
12 DBL If the block wait time is exceeded, you can select the
maximum number of repititions for the request frame via
the DBL parameter. If these trials are not successful, the
transfer is aborted.
1 ... 255 (0x01 ... 0xFF)
0x00
Option 8, priority
13 Priority A communication partner has high priority if the
transmission attempt has priority over the partner's request
to transmit. With a low priority, the partner's request to
transmit comes first.
In case of 3964(R), both partners must have different
priorities. You have the following setting options:
0x00: Low
0x01: High
0x00
Option 9 ... 12, reserved
