Service requests such as read point, setpoint, read address and write address as well as point initialization are performed synchronously.
Defaults are as follows.
|
Default behavior |
Use the defined maximum asynchronous age request. This value is defined by the logical DCQ_DEAD_TIME (the units are automatically converted to ticks to ensure equivalence). |
|
Default value |
If no value is defined, the default value is 2 minutes. |
The logical controls how long (in ticks) Mitsubishi TCP/IP communications will wait for a synchronous response from a device, once the request has been made of the device.
To change the time-outs:
For
all devices on a single port:
Add the following records to the log_names.cfg file.
<PORT>_MSYNC_TICKS|P|default|10|<ticks>
For
all devices in a selected project:
Add the following records to the log_names.cfg file.
MSYNC_TICKS|P|default|10|<ticks>
MMAX_SYNC_TICKS|P|default|10|<ticks>
Where
<ticks> is the time delay represented in ticks. 1 tick = 1/100 seconds
Important: The order of precedence for the
logicals is:
<PORT>_MSYNC_TICKS (port defined logical).
MSYNC_TICKS (project-wide defined globals).
MMAX_SYNC_TICKS (project-wide defined globals).
DCQ_DEAD_TIME (default).
Note: It may be necessary to increase the number of ticks to 50 if the Mitsubishi TCP/IP driver is timing out with errors.
