Several of the network directives are intended for internal use only, as
indicated in the detailed descriptions which follow. They have been included
here for completeness.
< D – Show Unit Display
Is used to request what is currently on the display of the workstation
addressed. In the example below, it is the status line.
Directive: < D
Response: 0808001600ND D 8-8 Ready ––Online [M] ? 45
< E – Show Last Error Message
Requests the text of the last error message issued from the language
interpreter at the workstation addressed.
Directive: < E
Response: 0808001600ND E ERROR 03 UNKNOWN AT 255.00.00
TIME OF ERROR ... 1742478802056
< R – Show Last Reset Message
Request the text of the last ‘reset’ error message. If a recoverable “reset”
condition occurs, this message is automatically generated. The < R directive
can then be used to see it again.
