Third Party Networking

Third party communication and networking troubleshooting

should be done by or with assistance from the front end 3rd

party technician. A Module Status Report (Modstat) can be

run from Field Assistant (see Table 5 to perform). This lists

information about the board status and networking state. For

basic troubleshooting, see Table 6.

For further information about third party networking contact

“Serial No: OR2YMCxxxP ”

(Bar Coded & Typed Number)

The serial numbers are unique and contain embedded information, for example OR2420042P:

“OR2” --- These first three digits are unique to RTU Open and are used as an identifier.

“YM” --- These two digits identify the last digit of the year and month (in hex, A=10/Oct)

of manufacture. “42” would represent a date of manufacture of “Feb 2014”.

“C” --- T h o u s a n d s c o u n t e r 0 --- 9 a n d A --- Z ; A = 1 0 ; Z = 3 5

“xxx” --- These three digits represent the sequential number of units produced for a given

product for the mentioned manufacturing time period.

“P” --- This final digit represents the decade and toggles between “N” and “M” every

ten years.

Check RS485 bus for external voltage

before reconnecting to the bus.

Verify devices are daisy chained and repeaters and bias
