If the programming tool is connected to the both connectors, the following phenomena may
occur.
1 ) A program in the programmable controller may be different from a program in the
programming tool. If the program is modified or the set value of a timer, counter, etc. is
modified in this status, a part of the program may be damaged and the programmable
controller may malfunction.
2 ) If the sampling trace function provided in the programmable controller is used in the both
ports, correct sampling trace results cannot be obtained.
