As the software version E or later uses the extended service mode, the new setting position "No.
E" was added to the MODE setting switch.
If the MODE setting switch on the A1SJ71PB92D of the software version D or earlier is set to No.
E, we cannot guarantee its operation. Do not set the MODE setting switch of the software version
D or earlier to No. E.
(2) The operation mode changing function and MELSEC ProfiMap's remote parameter function
were added to the software version G.
