PLC
Instrument Setup Protocol: 19,200 Baud, 8 Character bits, 1 Stop bit, and no parity.
This is a continuous output that transmits data on every other A/D update
(approximately 32
transmissions per second.
The output string is 12 characters, seen as "wwwwwwwuumm<eot>" where,
<wwwwwww> = Weight including decimal point and negative sign.
Negative sign precedes most significant digit and may be preceded by space
characters.
<uu> = units "lb", "kg", "oz", or "g ". "oz" may indicate ounces, or lb/ounces.
<mm> = mode "GR" or "NT" for stable weight, or "gr" or "nt" for motion.
<eot> = end of text.
Example 1: Gross - lbs - Weight Stable
<WWWWWWW> <l><b> <G> <R> <EOT>
Example 2: Gross - lbs - Weight in Motion
<WWWWWWW> <l> <b> <g> <r><EOT>
Example 3: Net - kgs - Weight Stable
<WWWWWWW> <k> <g> <N> <T> <EOT>
Example 4: Net - kgs - Weight in Motion
<WWWWWWW> <k> <g> <n> <t> <EOT>
Note: Once PLC option is selected and protocol has been programmed, the installing
technician's setup is complete. Confirmation of output can be performed by
monitoring the COM port with a terminal program such as Windows Hyper Terminal.
Note: Interface of the HMS Communications device, power supply to same device,
and programming of the PLC is strictly the responsibility of the customer.
