8.3 Function
2. Error Status 2, Error Count 2
A response is returned when an error is detected in the application. Error Status 2 and Error
Count 2 are updated as well. Error Count 2 counts from 0 to 255 and then goes back to 0.
By setting to 1 the remote reset status or the reset switch of the UPM100’s main body, Error
Status 2 and Error Count 2 are initialized (in other words, they are set to &H00, which means
there are no errors).
• When an unauthorized value is assigned
When VT ratio, CT ratio, pulse width, or pulse weight is set to an out-of-range value, bit5 of
the status of the response is set to 1. The current value of the data remains the same. By
reading out the status of the error immediately after its occurrence, it is possible to confirm
that bit4 of Error Status 2 in the User Controlled Items is set to 1.
• When an unauthorized command is executed
bit7 of the status of the response is set to 1. Also, one of bit0 to bit3 of Error Status 2 is set
to 1.
