Modes of Operation
All controller modes are considered to be remote, which indicates that the
modes can be changed via the communication channels.
The current mode of the controller is shown in the upper right-hand corner of
the MicroLogix 1000 HHPs home screen. The table below shows the
possible display entries and the corresponding micro controller mode.
Display Entry Micro Controller Mode
RPRG Remote Program
RRUN Remote Run
RCSN Remote Test – Continuous Scan
RSSN Remote Test – Single Scan
RSUS Remote Suspend
➀
FLT Fault ➁
➀ The controller only enters suspend mode if you run a program that executes a suspend instruction.
➁ The controller only enters fault mode if, while a program is executing, a fault occurs within the operating
system or the program, or setting S1/13 in any mode. See page 20–11 for information on identifying and
clearing faults.
You can place the micro controller in remote program, run, and test modes
using the mode key. Each of these modes is described below. (Changing
modes is described on page 18–22.)
Remote Program Mode
The remote program mode (RPRG) allows you to modify your program, edit
data, and transfer programs to and from the memory module. In this mode
the processor does not scan or execute the ladder program and all outputs are
de-energized.
Remote Test Mode
While you are in the remote test mode, the controller monitors input devices,
scans or executes the program, and updates the output data files without
energizing output circuits or devices. There are two remote test modes
available:
•
Remote Continuous Scan (RCSN) – This test mode is the same as the
remote run mode (described below), except output circuits are not
energized. This allows you to troubleshoot or test your program without
energizing external output devices on a continuous basis.
•
Remote Single Scan (RSSN) – In this test mode, the controller executes
a single operating cycle that reads the inputs, executes the program, and
updates all data without energizing output circuits.
Remote Run Mode
While you are in the remote run mode (RRUN), the controller monitors input
devices, scans or executes the program, energizes output devices, and acts on
enabled I/O forces.
