TECHNICAL NOTE
Block error condition:
The following table outlines several situations that may cause an error, and will turn on
the blocks “Error” output bit. The block “Error” output will cleared if the EXECUTE bit
goes low.
Fault bit Cause Note
inOK
AB00000D Machine Cycle
input is out of
range inOK must be high if enable is on
or an error will occur. MCHNCYCL
must be in range for this bit to be
on. Sets RDA Error ID (MW30181)
bit 3.
msSelect
AB00000E
M-S-PAIR
input
value out of
range
msSelect must be high if enable is
on or an error will occur. M-S-PAIR
must have a value from one to ten
for this bit to be on. Sets RDA Error
ID (MW30181) bit 3.
Working Registers
This table outlines the data in the eight registers used by the function block. There is
not usually any need for the user to access any of these bits directly.
