The Get System Status microblock can be used to indicate Read or Write errors in certain microblocks, and whether any microblock within the control program is Locked.
Read Error If you choose Read Error in the Initial Type section, then the microblock has a True value only when a Network Input microblock or an Analog Properties microblock in the same control program indicates an error condition. This includes Analog Network Input, Analog Network Input 2, Binary Network Input, Binary Network Input 2, Average Analog Properties, Maximum Analog Properties, Minimum Analog Properties, and Total Analog Properties microblocks.
Write Error If you choose Write Error, then the microblock has a value of True only when a Network Output microblock in the same control program indicates an error condition. This includes Analog Network Output, Analog Network Output 2, Binary Network Output and Binary Network Output 2 microblocks.
Point Locked If you choose Point Locked, then the microblock has a value of True only when points in the same control program are currently locked.
The microblock's value is True or False. The Get System Status function may be used to send notice of these conditions to Alarm microblocks.
