Token Hold Timer
Set the time held from when the station receives a token until token transmission at 1~65 ms (1 ms units).
Link data and message data transmission is possible during token holding. In cases where there is no data to be
sent, the tokens will be sent to the next station even if the token holding time setting is not met.
When hold timer is short, message transmission may not be possible.
Token Receive Timer
This is set in order to monitor the data transmission from the station in the PCLINK network. Set the timeout time in
a range of 50~2550 ms (10 ms units) from the previous data reception until the next data reception. If no data is
received in this set time, that station will be treated as an error.
Station Search Interval
This sets the search interval for detecting new stations in a range of 100~25500 ms (100 ms units). The station will
search whether any new stations have come on-line.
Discrete Offset
This sets the lead offset address of the link coils in a range of 000 H~800 H in order to differentiate the I/O registers
as link register fields and link coil fields. The I/O register lead number + this setting becomes the lead of this link coil
field. Caution is necessary, as the link register fields and coil register fields may overlap according to the settings.
There is no overlap between the link register fields and the link coil fields at 800 H.
MEMOBUS Monitoring
Set the time until the MEMOBUS message transmission detects a communication timeout in the range of
0~25500 ms (100 ms units). Setting zero (0) will result in an indefinite wait.
Retry Count
Set the number of retries after detection of MEMOBUS message transmission communication timeout in the range
of 0~3. The set number of retries will be performed after communication timeout, and if no response is still obtained,
a message communication error will be detected.
Transmission Speed
Set the PCLINK-01 transmission baud rate in the range of 0.5/1/2/4 Mbps.
