MODULE_INFO

The MODULE_INFO instruction reads module information from a plug-in module or an expansion module.
Operation details:
  • Plug-in module information is read during Run time.
  • The 2080-MEMBAK-RTC memory plug-in module is not supported.
  • Expansion module information is read when the module is powered on.
  • When a plug-in or expansion module is not defined with a ModuleID, ProductType, or ProductCode, the MODULE_INFO operation returns 0 for the respective output parameter.
  • The plug-in and expansion module identification information is defined by Allen-Bradley and is provided below as part of the MODULE_INFO description.
Languages supported: Function block diagram, ladder diagram, structured text.
This instruction applies to the
Micro820
 L20E,
Micro850
 L50E, and
Micro870
 L70E controllers. Expansion modules are only supported on the
Micro850
 L50E and
Micro870
 L70E controllers.

Error
Output
BOOL
Indicates the existence of an error condition.
  • TRUE: An error is detected.
  • FALSE: No error.
ErrorID
Output
USINT
A unique numeric that identifies the error. The errors are defined in the MODULE_INFO error codes.
