SERIAL LINK
The device can be connected to a host computer by a serial link.
The host can put the device in LOCAL (functions and parameters are controlled via keyboard) or in REMOTE (functions and parameters are controlled via serial link).
The REMOTE status is signalled by the decimal point (labelled REM) at the right hand of the LSD of the upper display.
This instrument allows to modify the operative and configuration parameters, via serial link. The necessary conditions to implement this function are the following:
1)Serial parameters from SEr1 to SEr4 should be properly configured using the standard front keyboard procedure
2)Device must be in the OPERATING mode
During the downloading of configuration the device goes in open loop with all output in OFF state.
At the end of configuration procedure, the device performs an automatic reset and then returns to close loop control.
SMART function
It is used to optimize automatically the control action.
To enable the SMART function, push the FUNC pushbutton until "Snrt" parameter is shown. Pushing s or t set the display "On" and push the FUNC pushbutton.
The SMRT LED will turn on or flashing according to the algorithm selected.
When the smart function is enabled, it is possible to display but not to modify the control parameters.
To disable the SMART function, push the FUNC pushbutton again until "Snrt" parameter is shown. Pushing s or t set the display "OFF" and push the FUNC pushbutton.
The SMRT LED will turn off.
The instrument maintains the actual set of control parameters and it enables parameter modifica- tion.
NOTES : 1) When ON/OFF control is pro- grammed (Pb=0), the SMART function is disabled.
2)The SMART enabling/disabling can be protected by safety key (see P30).
