RSView32 commands  A–41

Tag Write category. Specify where to send Tag Write

errors using the Categories tab of the Activity Log

Setup editor.

<tag_name> The name of an analog tag.

<value> The amount to add or subtract from the current

programmable controller value, as follows:

plus (+) or minus (-) a numeric value

plus (+) or minus (-) a percentage of a numeric

value in the form: +value%

plus (+) or minus (-) a tag

If Ramp calculates a value that is outside of the tag’s minimum and

maximum range, it will write the highest or lowest allowable value to

the programmable controller or server.

Examples: The Ramp command

Ramp Hopper1\Level +50%

If the value of Hopper1\Level is 100, Min = –100 and Max = 900, the

command writes the value 600 to the programmable controller.

Ramp Hopper1\Level +75%

If Hopper1\Level is 900, Min = 0 and Max = 1000, the command

writes 1000 to the programmable controller because this is the highest

allowable value.

If you use the Ramp command in a macro, you must use two percent

signs (%%) instead of one. A single percent sign is used in a macro

to indicate a parameter. For example, to create a macro that

increases the value of tag1 by 75%, you would type: Ramp tag1 +

75%%
