Bypass Enable The normal control algorithm can be bypassed using the
BYPASS parameter. When bypass is set the Set Point value, in
percent, is directly transferred to the output. To prevent a bump
on transfer to/from bypass, the Set Point is automatically initial-
ized to the output value or process variable and the path broken
flag is set for one execution. BYPASS is not permitted unless the
BYPASS ENABLED option is set.
SP-PV Track Man Permits the Set Point to track the process variable when the tar-
get mode of the block is Man.
SP-PV Track ROut Permits the Set Point to track the process variable when the
actual mode of the block is ROut.
SP-PV Track LO-IMan Permits the Set Point to track the process variable when the
actual mode of the block is LO or IMan.
