KEYENCE KV Series - Manual (Page 6)

Cautions when using the previous version of ladder support software
Pay strict attention to the following items when using the ladder support software.
• When using the ladder support software "KV IncrediWare (DOS)" or "LADDER
BUILDER for KV Ver. 1.0x", set the model to "KV-300".
• DM0 to DM1999 are only available.
When the ladder support software "LADDER BUILDER for KV Ver. 1.0x" is
used, do not use the monitor’s Change All function. If the Change All function
is used, the basic unit may be damaged. Never use the Change All function.

Cautions when Using the Serial Port

serial communication.
When using them, pay strict attention to the following contents:
• Programs can be transferred and monitored using either communication port A or
B. However, never connect the ladder software and a handheld programmer to
the two ports at the same time.
• The KV-D20 operator interface panel can be connected to either communication
port A or B. However, only one KV-D20 unit can be connected to a single basic
unit.
• Never leave both the KV-D20 operator interface panel and KV-P3E(01) handheld
programmer on simultaneously for a long period of time.
