Santerno Sinus Penta - Table 91: Remote Command Inputs from Serial Link

SINUS PENTA
PROGRAMMING GUIDE
308/486
NOTE
If the keypad is enabled as a command source, the START, STOP, RESET, LOC/REM,
FWD/REV functions are enabled (to disable LOC/REM and FWD/REV
see parameter
P269
). The keypad is ignored for the processing of logic functions (AND/OR) of the other
command sources that are enabled at that moment.
NOTE
As the ENABLE-A and ENABLE-B commands of the physical terminal board are a
hardware safety device (they enable the drive) they are
always active, even when none of
parameters C140, C141 or C142 selects the terminal board (=1).
If the STO function is to be adopted, the control mode and the control circuit of these
signals must be accomplished as per the Safe Torque Off Function - Application Manual.
That manual also includes a detailed validation procedure of the control configuration of
the STO function to be executed upon first start-up and also periodically at yearly intervals.
NOTE
The commands for the External Alarm n.1, n.2, n.3 functions
are always considered for
the drive terminal board only.
NOTE
The LOCAL mode, that can be enabled with the LOC/REM key from the keypad or with
the LOCAL command function from the terminal board (see C180
), forces the keypad as
the only command source, thus ignoring the values set in parameters C140, C141, C142.
The following functions are therefore enabled for the hardware terminal board: External
Alarm n.,1 n.2, n.3 (C164, C165, C166), Motor Sel. n.2 (C173), Motor Sel. n.3 (C174),
SLAVE (C170), Source Selection (C179, C179a, C179b), LOCAL (C180) and the
ENABLE-A and ENABLE-B and RESET functions are always enabled for terminals MDI2,
S and MDI3.
The ENABLE-SW and DISABLE
functions are enabled in LOCAL mode if at least one of
parameters C140, C141, C142 is set to 1 (terminal board).

Remote, virtual terminal board

Example:
If C140 = 3 (Fieldbus) and C141 = 2 (Serial link), the ENABLE command is sent by closing terminals ENABLE-A and
ENABLE-B on the terminal board and (AND) by forcing bit MDI2 from the serial link on input I019 (MODBUS address:
1406) and bit MDI2 from Fieldbus (see the FIELDBUS CONFIGURATION MENU).
The START command may also be sent (OR) by forcing bit MDI1 from serial link on input I019 or by forcing bit MDI1
from Fieldbus for the relevant variable.
