Defining Add-On Instructions

Chapter 2

Project documentation that supports multiple translations includes these

variables:

• Component descriptions in tags, routines, programs, equipment phases,

user-defined data types, and Add-On Instructions

• Engineering units and state identifiers added to tags, user-defined data

types, or Add-On Instructions

• Trends
• Controllers
• Alarm Messages (in configuration of ALARM_ANALOG and

ALARM_DIGITAL tags)

• Tasks
• Property descriptions for module in the Controller Organizer
• Rung comments, SFC text boxes, and FBD text boxes

If you want to allow project documentation on an Add-On Instruction that is

sealed with an instruction signature, you must enter the localized documentation
into your Add-On Instruction before generating the signature. Because the

signature history is created after the instruction signature is generated, the

signature history is not translatable. If the translated information already exists

when you generate the Add-On Instruction signature, you can switch the language
while keeping the signature intact because the switch does not alter the instruction

definition, it only changes the language that is displayed.

For more information on enabling a project to support multiple translations of

project documentation, refer to the online help.

The Motor_Starter Add-On Instruction starts and stops a motor.

If the stop pushbutton is closed and the start pushbutton is pressed then:

• The motor gets the command to run.
• The instruction seals in the command, so the motor keeps running even

after you release the start pushbutton.
