Communications Functions Section 1-6
This is because, in order to write data to the CPU Unit, the PT changed the
operation mode from RUN mode to MONITOR mode. To continue operation
using the Programming Console, it is necessary to input the password again.
Inputting the Password
• The mode will not be changed if the PT is connected via an NT Link.
• When a Programming Device installed on a computer is connected to the
peripheral port, the display (at the computer) for the CPU Unit’s operation
mode will simply change from “RUN” to “MONITOR.”
1-6-1 Host Link and No-protocol Communications Settings
This section explains the PC Setup settings that are shared by the Host Link
and no-protocol communications modes. Make the required PC Setup set-
tings before attempting to establish Host Link or no-protocol communications.
Note If pin 5 on the CQM1H’s DIP switch is turned ON, the PC Setup communica-
tions parameters will be ignored and the following settings will be used.
The PC Setup parameters in DM 6645 through DM 6654 are used to set
parameters for the communications ports.
