■ Mode transition restrictions
Modes can be changed using console keys, external switch inputs or through
communications. The table below shows the operations that are valid for each
mode.
❍ : Valid operation
❁ : Operation from basic display status
valid
∆ : Returns to the first segment remaining
in the READY mode.
❑ : Operation is invalid, but the
communication end code is normal if
performed in the basic display status.
– : Invalid operation
* ADV operation performed via communications may not go to the next segment
but to the segment set in the communications message.
Handling Precautions
•Mode transitions can be simultaneously performed for both CH1 and CH2
under the following conditions.
•When key operations are performed in synchronous mode (PA04=1).
•Switch operations performed when both the CH1 operation cancel
switch (SW15) and the CH2 operation cancel switch (SW16) are set to
OFF.
•When a write command is used to communicate with 2001 status 1
(CH1 and CH2).
•Mode transitions can be simultaneously performed for either CH1 or CH2
under the following conditions.
•
When key operations are performed in asynchronous mode (PA04=0).
•
Switch operations performed when either the CH1 operation cancel switch
(SW15) or the CH2 operation cancel switch (SW16) is set to ON.
•When a write command is used to communicate with 261 status 1
(CH1) or 281W status 1 (CH2).
