RSLogix 500 RSS file size difference when backing up?
Cmdr_Suds replied to bwhinch's topic in Allen Bradley / Rockwell Automation
Depending on how the file was lasted saved, online or offline, the .rss file may have an online and offline copy of the ladder file thus accounting for the difference in various file sizes. -
Maybe go down to the local pub and ask if there are any control engineers hanging around. Hope this helps.

Verify the power supply jumper is set to the correct voltage otherwise the processor will behave badly -
Micrologix talking to Schneider Drive

Be careful using the on board analog input of the 1100. It only has 10 bits of resolution. depending on you operating parameters, it might provide for some jerky control. -
Need help concern panel view 550 keypad
Cmdr_Suds replied to Ayman's topic in Allen Bradley / Rockwell Automation
DH485 is the protocol (language). the SLC 5/04 will talk DH485 out the RS232 port but you need the AIC to electrically convert the signal to RS485 that the PV comm port uses. The AIC is not a protocol (language) converter, only an interface converter -> RS232 to RS485. -

RSLogix 500 multiple Bit Shift
Cmdr_Suds replied to Antony17's topic in Allen Bradley / Rockwell Automation
Dividing the source by 256 will effectively shift the bits 8 places to the right. You may need to pass it through a MVM to clean up the results.
