Does the M580 support system words, %SW138 to %SW141
The M580 PAC does not support the system words, %SW138 and %SW140. These system words were added to only the M340 to facilitate the migration from LL984 to M340. With a M340 these four System Words were added to offset the starting address of variables which are accessed by Modbus requests. However, the M580 does support the system words, %SW139 and %SW141 but requires the M580 CPU to use firmware 2.10 IR15 or higher.
