On power-up or after one of the following commands:
The controller display unit and the ClsM2 "front panel" appear as follows:
The screen comprises the following 5 lines:
Description of the 1st line on the display: Icons
:
"On/off", in rotation, when the controller is in ON mode, the speed of
rotation is inversely proportional to the duration of the
basic cycle time of the controller.
:
"Memory Card in active use", only appears when program data is being
exchanged between the controller and the memory card. You are strongly
advised against removing the memory card inserted in the controller whilst
this icon is being displayed. If you remove the card, you risk destroying the
program entirely or partially, thus creating an unpredictable and dangerous
situation.
:
"Error(s) saved", indicates that at least one error has occurred on the
controller since the last command to clear all errors.
:
"Connection with CLS M2 active", indicates that the controller is
currently exchanging data with the CLS M2 programming application either
directly via a link or indirectly via a modem.
:
"Protection Active", indicates that the user must enter a password to
access the various parameterisation and configuration menus of the controller
via the buttons on the front panel.
:
Power supply, appears as soon as the controller is connected to the
power supply, indicating that power is being supplied to the display unit.
indicates the active state (ON) of a digital input or
output
indicates either the inactive state (OFF) of a digital input
or output, or an analog input or PWM output whatever its state may be (*)
Each symbol, read from left to right, corresponds to a controller input or output starting at I1 for the inputs and O1 for the outputs.
Note:
The states of the digital inputs and outputs of certain specific Local and Contiguous Extensions (XL 05 examples: 4 solid state outputs, XC 01 4 inputs/2 relay outputs) can be displayed. Pressing the + button once or twice will display the state of the inputs/outputs on the XL extension then the XC extension connected to the controller respectively. Pressing the - button once or twice will return to the display of the inputs/outputs on the XL extensions or the controller respectively.
On the 3rd line of the display, the letter I followed by an arrow designates the 2nd line, i.e. the state of the inputs, and the next two characters designate the element whose I/O state is being displayed on the 2nd and 3rd lines, i.e. M2 for the controller, XL for the local extension and XC for the contiguous extension (if applicable).
Note:
Depending on the type of controller or extension, all the inputs and
outputs displayed may not necessarily be physically present on the
corresponding unit or may not correspond to the digitals and will remain
displayed as .
On the 3rd line of the display, the letter I followed by an arrow designates the 2nd line, i.e. the state of the inputs, and the next two characters designate the element whose I/O state is being displayed on the 2nd and 3rd lines, i.e. M2 for the controller, XL for the local extension and XC for the contiguous extension (if applicable). This line also contains the current time (hours and minutes) of the controller clock.
On the 4th line of the display, the current date appears in the format selected in the CLS M2 "Options | Date format" and "Controller | Read/write date and time" command.
