4-1 Using a Programming Console
This section provides information on connecting and using a Programming
Console. Refer to
5-3 Programming Console Operation Errors for details on
errors that might occur during Programming Console operations.
4-1-1 Connecting the Programming Console
A Programming Console can be connected to the CPM2C’s communications
port or the peripheral port on a CPM2C-CN111 Connecting Cable; it cannot
be connected to the CPM2C-CN111 Connecting Cable’s RS-232C port.
Note The setting of SW2 will affect the startup operating mode for all Units with lot
numbers of 3180O (31 August 2000) or earlier. Refer to
1-7 Changes in SW2
for details.
a) With CPU Units with lot numbers of 3180O or earlier, before connect-
ing the Programming Console, turn OFF Communications Switch
(SW2) on the front of the CPM2C CPU Unit. The PRO indicator will
light.
b) If SW2 is turned OFF for a Programming Console connection, a PT
cannot be used in PT Programming Console Mode connected to the
RS-232C port. Turn ON SW2 to specify that a Programming Console
will not be connected before attempting to use PT Programming Con-
sole Mode for the RS-232C port.
c) Do not change the setting of SW2 when a Programming Console,
CPM2C-CIF01-V1, CPM2C-CIF11, CQM1-CIF01, or CQM1-CIF02 is
connected. Communications will be disconnected if the switch setting
is changed, causing a communications error or causing the Program-
ming Console not to respond (i.e., the display will not change when
keys are pressed).
