6.4.1.1 Auto/manual control
The auto/manual control element manages the auto/manual control mode, consolidates
the start A, start B and stop controls from their various sources, and applies auto/manual,
test switch and permissive supervision.
The MM300 has four possible sources of start A, start B and stop controls:
Communications: Controls received over a serial data link - Modbus, DeviceNet,
Profibus and/or Modbus TCP. Communications controls are not differentiated based
on port or protocol.
Hard-wired: Controls received typically via contact inputs from a PLC or DCS.
Field: Controls received typically via contact inputs from pushbuttons or switches
located adjacent to the controlled equipment.
MCC: controls received from the control panel of the MM300.
Communications and hard-wired controls are considered to be auto controls, and are
inhibited unless auto mode is on. Likewise, field and MCC controls are considered to be
manual controls, and are inhibited unless manual mode is on. Each source may also have
a contact input assigned to permissive supervision, which enables that source when on.
Table 5: Auto/manual control sources
The MM300 may also be set to always honor stop controls, regardless of auto/manual
mode and permissive supervision (default).
The auto/manual control element also drives a control source active indicator for each
source on the front panel display (if equipped) that shows the user exactly which control
sources have both the correct auto/manual mode on and have their permissive configured
and on.
