SIMO_CHN Function
3.1 Description
3.1.15

Reset Response

When SIMOCODE-DP detects a fault, it signals this through the general fault output
(QG_FLT). Faults must be acknowledged through linkable input L_SIMORESET, or input
SIMO_RESET, which can be controlled from the OS.
Some faults can also be acknowledged by an OFF command. In control function VALVE and
POS, some faults can only, or also, be acknowledged by a counteraction (OPEN or CLOSE).
For a detailed overview of how the various faults are acknowledged, please refer to the
SIMOCODE-DP manual, chapter 5.2, p. 5-4.
3.1.16

Additional Functions

This block provides two additional outputs QADD_F1 and QADD_F2 which can be controlled
and monitored. Operator control is through inputs ADDF1 and ADDF2, and operator
enabling is performed through the two inputs ADDF1_EN and ADDF2_EN (QADDF1OP and
QADDF2OP). These additional functions do not affect the internal block functions, and can
be used for controlling any of the binary signals.
3.1.17

Startup Response

After CPU startup (restart), the current statuses for LOCAL/REMOTE, MANUAL/AUTO,
MANUAL OPERATOR/MANUAL LINKED are retained. Commands are not output again.
Depending on the configured SIMOCODE-DP error response, a CPU STOP either causes a
SIMOCODE-DP fault (default setting), or (if "response PLC-CPU fault: retain status" is set)
causes the current mode status to be retained.
After startup, the number of cycles configured in the RUNUPCYC block I/O are inhibited.
3.1.18

Time-related Characteristics

The block must be called through a watchdog interrupt OB. The block sampling time is set in
parameter SAMPLE_T.
3.1.19

Bumpless Changeover

A command is reset in the block if the associated check-back signal is present.
Consequently, operating inputs ON1_OP, OFF_OP, and ON2_OP do not have to be tracked.
However, mode selections REMON_OP, AUTON_OP, and MANON_OP are always tracked
in the active settings.
