2.3.9 Cyclic Data Transmission
0 to 4,294,967,296 (2 raised to the power of 32) milliseconds
This parameter defines the number of milliseconds between cyclic updates. The
range of values allow for update times between 1 millisecond and 49.7 days. Set
this parameter to 0 to disable cyclic data reporting.
2.3.10 Select/Operate Timeout
0 to 4,294,967,296 (2 raised to the power of 32) milliseconds
This parameter sets the number of milliseconds to wait for a valid Execute
command after receiving a Select command. The range of values allows for
update times between 1 millisecond and 49.7 days. Set this parameter to 0 to
disable this feature.
2.3.11 Use ACTTERM with Set Point
Y - Y ES or N - N O
This parameter determines if an ACTTERM will be sent. If the parameter is set to
Y
ES , then Set point commands will issue an ACTTERM when the command is
complete. If the parameter is set to N O , ACTCON is the last response to a Set
point command.
2.3.12 Use ACTTERM with Step
Y - Y ES or N - N O
This parameter determines if an ACTTERM will be sent. If the parameter is set to
Y
ES , then Step commands will issue an ACTTERM when the command is
complete. If the parameter is set to N O , ACTCON is the last response to a Step
command.
2.3.13 Single char ACK F0, 1 or 3
Y - Y ES or N - N O
If set to Yes, a single character ACK (0xE5) will be sent instead of a fixed length
ACK (secondary function code 0) in response to a primary link function code 0, 1
or 3 if there is no access demand for class 1 data (ACD=1). If set to No, the fixed
length ACK will be sent.
2.3.14 Single char ACK C1 or C2
Y -Y ES or N - N O
If set to Yes, a single character ACK (0xE5) will be sent instead of a fixed length
NACK (secondary function code 9) when no response user data is available. If
set to No, the fixed length NACK will be sent.
