Type Communication parameter
Syntax HLM_TIMEOUT
Description The HLM_TIMEOUT parameter specifies the fixed timeout time for
the Host Link Master protocol for both serial ports. A timeout error
will occur when the time needed to both send the command and
receive the response from the Slave is longer than the time speci-
fied with this parameter.
The parameter applies for the HLM_READ, HLM_WRITE and
HLM_COMMAND commands. The HLM_TIMEOUT parameter is
specified in servo periods.
Arguments N/A
Example >> HLM_TIMEOUT=2000
Consider the servo period of the TJ1-MC__ is set to 1 ms
(SERVO_PERIOD=1000). For both serial ports the Host Link Mas-
ter timeout time has been set to 2 s.
