2. First relay no. +1
Turns ON and remains ON when the loaded data cannot be transferred to data
memory because the first relay no. +0 is ON when the data is received, or a parity
error has occurred (that is, first relay no. +2 was ON) during data reception.
When the data is loaded while the first relay no. +1 is ON, the first relay no. +1 turns
OFF when the first relay no. +0 turns ON.
To fetch the ON signal only for one scan, change the program as shown in 1. First
relay no. +0, above.
3. First relay no. +2
Turns ON and remains ON when the data cannot be received because a parity error
has occurred during data reception. (The first relay +0 turned ON simultaneously.)
When the data is loaded while the first relay no. +2 is ON, the first relay no. +2 turns
OFF when the first relay no. +0 turns ON.
To fetch the ON signal only for one scan, change the program as shown in 1. First
relay no. +0, above.
