Connecting the Programming Console Section 7-2
7-2-3 Operating Mode at Startup
The operating mode of the CQM1H when the power is turned ON depends
upon the PC Setup settings and the Programming Console’s mode switch set-
ting if a Programming Console is connected.
Note If pin 7 on the DIP switch is ON, the above information may change depending
on other settings in the PC Setup. Refer to Section 6-2 Communications Port
and Startup Modes Settings for details.
7-2-4 Preparation for Operation
This section describes the procedures required to begin Programming Con-
sole operation when using the Programming Console for the first time.
!Caution Always confirm that the Programming Console is in PROGRAM mode when
turning ON the PC with a Programming Console connected unless another
mode is desired for a specific purpose. If the Programming Console is in RUN
mode when PC power is turned ON, any program in Program Memory will be
executed, possibly causing a PC-controlled system to begin operation.
The following sequence of operations must be performed before beginning ini-
tial program input.
1,2,3... 1. Be sure that the PC is OFF.
2. On the DIP switch on the front of the CPU Unit, set pin 7 to OFF to enable
a Programming Console Connection and make sure pin 3 is ON for English
language displays.
3. Connect the Programming Console to the CPU Unit’s Peripheral port. See
7-2 Connecting the Programming Console for details.
(The CPU Unit’s Communications Switch setting has no effect on commu-
nications with the Programming Console.)
4. Set the mode switch to PROGRAM mode.
5. Turn ON the PC.
6. Enter the password. See 7-2-5 Entering the Password for details.
7. Clear (All Clear) the PC’s memory. See 7-3-2 Clearing Memory for details.
8. Read and clear all errors and messages. See 7-3-3 Reading/Clearing Er-
ror Messages for details.
9. Start programming.
7-2-5 Entering the Password
To gain access to the PC’s programming functions, you must first enter the
password. The password prevents unauthorized access to the program.
The PC prompts you for a password when PC power is turned ON or, if PC
power is already ON, after the Programming Console has been connected to
the PC. To gain access to the system when the “Password!” message
appears, press CLR and then MONTR. Then press CLR to clear the display.
