APPENDIX D - TEXT STRINGS & NUMERIC VALUES VIA ASCII MODE

The GS120 can also be confi gured to display numeric values and text strings from a

PC or PLC using a simple ASCII protocol.

For this mode to function:

The optional RS232 serial card must be installed in Com 2 (see order codes in

Section 1)

AND

Both

Com 1

and

Com 2

must be set to

Disabled

in 6.2D.

The

Com 2

port can then be used to connect the GS120 to your PC or PLC device.

Com 2

will revert to a simple ASCII mode operating at 115,200 baud, 8 data bits, no

parity, 1 stop bit.

Writing a numeric display value

To write the numeric value 12345 to the display, the following string should be sent

to the GS120:

s w 7 , 1 2 3 4 5 *

Start character

Write command

Separator character

1 2 3 4 5

Numeric value you want on the display

End character

To write numeric values to the display, the User 1 input function must not be set to
counter (see 6.4B).

Writing text strings

To write a text string to the display, the format is identical to that above, except that

the register address for a text string write is 16389, and instead of a numeric value,

alpha/numeric characters are used:
