PROGRAMMABLE FUNCTIONS (Cont’d)

INDICATION DISPLAYS (Cont’d)

Custom Display Line:

The Legend Plus has two Custom Display Lines which allow the user to 
specify the number of digits to be displayed on the line, along with any alpha-
numeric prefix or suffix.

Program Mnemonic:

Allows the user to modify the mnemonics (RATE, PROCESS, BATCH, etc.) 
to a mnemonic of your choice. For example, RATE can be changed to read 
SPEED.

MESSAGES

There are ten messages that can be programmed in the Legend. The following 

attributes can be set for each message.

Message Text:

Standard Characters

 - Lower/Upper case letters, numbers, punctuation 

symbols

Extended Characters 

(Including most European characters)

Message Priority:

1 to 8 (1 = highest priority)

Message Type:

1 line block

 - message scrolls in block fashion on the top line of the display, 

bottom line contains programmed indication display.

2 line block

 - message scrolls in block fashion on both lines of the display

1 line scroll

 - message scrolls right to left on the top line of the display, 

bottom line contains programmed indication display 

2 line scroll

 - Top line scrolls right to left, bottom line is blanked

Maintained/Momentary Request:

A Maintained Request setting enables messages to be restored or 

redisplayed, when the display is available if the input/output action 
requesting the message is still active.

A Momentary Message setting will allow only one request per message 

requesting input/output action. Lower priority messages will be canceled by 
higher priority messages.

Blinking Message:

Enables the message to blink when displayed. Only available with 1 or 2 line 
block messages.

Multiplex:

Setting this parameter to yes will cause the unit to display the message for 2 
seconds, then display the programmed display for 2 seconds. Only available 
with 1 or 2 line block messages.

Message Cancellation:

The displayed message is canceled when:

A message of equal or higher priority is requested.
Message times out (Timed) and input/output is deactivated.
User input or output is deactivated (Til End).
User input programmed for clear message is activated.

Message Time:

Ranges from 1 to 599 Seconds.

Message Color:

 (Dual Color Option only)

Green or Red

COMMUNICATION PORT

Jumper selectable for RS-485 or RS-232

Baud Rate - 1200 to 9600
Parity - Odd (7 data bits), Even (7 data bits), or No parity (8 data bits)
Unit Address - 00 to 99
Transmit Delay - 0.002 or 0.100 seconds

PRINT OPTIONS

The programmable print options specify which values are transmitted when 

a print request is issued. The available options are; Rate, Peak, Valley, Count*, 
Process*, Batch*, Total*, Scale Factors, Preset(s), Counter Load values, and 
Message 0.

On Models with these available display options.

The unit can be programmed to transmit or NOT to transmit mnemonics (unit 

address & value identifiers). The mnemonic transmitted is the first three 
characters of the programmed display mnemonic. For total, only the first 
character is transmitted. A transmit and reset count capability allows the 
selected count values to automatically reset after the value is printed 
(transmitted).

OPERATOR ACCESS TO FRONT PANEL

There are several program disable modes that can be used to limit the 

operator from programming the parameter values via the front panel keypad. 
The Program Disable DIP switch can be used alone or in conjunction with a 
User Input, programmed for the program disable function and a programmable 
code value, to provide the desired level of security.

MODEL LGPB APPLICATION

A local canning plant wishes to improve the display and control capabilities 

of its nine process lines. There is a requirement to add message interaction for 
the operators during process operation. The following application facts and 
requirements have been specified by the plant engineer.

1. The cans are sensed by a photo-electric device specially suited for can 

manufacturing. The device produces one pulse per can.

2. The can count for the process of boxing the cans is the first requirement. 

The can count is never changed, there are always 24 cans to each box. An 
output is required at 20 cans to slow the line temporarily until the second 
output is turned on. The second output changes the gate direction to begin 
the next grouping of 24. The second output has a time delay output of 2 
seconds. After the time delay, both outputs are reset and ready for the next 
process cycle.

3. A count of the number of batches is required for each 8-hour shift. This 

count is recorded and reset by the manufacturing computer.

4. A total count of cans produced per 24-hour period is required. This count is 

also transmitted to the manufacturing computer, and reset as required via 
the communication link.

5. A display of cans per minute is required with minimum and maximum speed 

limits. Output 3 activates below 100 counts per minute and Output 4 
activates above 500 counts per minute.

6. The four desired displays are process, batch, total, and rate. These are to be 

scrolled via the front panel.

7. The customer also wants the following messages displayed when the listed 

events occur:
Output 3 - Line #4 Slow
Output 4 - Overspd STOP! (Wants this display to stand out and have top 

priority)

Proximity 1 - Check Label Glue
Proximity 2 - Check Top Supply
Proximity 3 - System Fault! Stop Line #4! (Wants this display to stand out 

and have top priority)

8. Once the unit is set up, the only front panel access should be for a reset of 

the process count and viewing of the displays.

Plus unit.
