Communication

NOTES

All commands mentioned in the subsections below are PI General

Command Set (GCS) commands in the E-517 syntax, provided by the

E-517 firmware.

This Quick Guide contains a list of the available commands in "E-517

GCS Commands, Alphabetically Survey" (p. 58). Detailed command

descriptions are provided by the E-517 User Manual which is on the

E-517 CD.

In a terminal, you get a list of available commands and their syntax by

typing HLP?. For a list of available controller parameters type HPA?.

4.2 Default and Current Settings

The default communication parameters are stored on the E-517. You can

read the default settings using the IFS? command and change them with

IFS. Changes become active with the next power-on or reboot, when the

default values are loaded into the controllers volatile memory (RAM).

The current active interface settings can be temporarily changed with IFC.

The new settings become active immediately and the host PC interface

configuration may need to be changed to maintain communication. When

the controller is powered down, the settings made with IFC are lost if they

were not saved with WPA.

To read all current active communication parameters use the IFC?

command.

NOTE

The IFS, IFS?, IFC and IFC? commands affect the controller side only.

It is also possible to change the default settings with SEP and to read them

with the SEP? command. If you use RPA to activate the changed settings, it

may be necessary to close the current connection and re-open it with the

new settings. The appropriate parameter IDs are given below.

The

factory defaults of the communication settings stored in the

controller are as follows (response to IFS?):

■ RSBAUD: gives the baud rate to be used for RS-232 communication,

default is 115200
