Memory Marker blocks output their input signal. IDEC SmartRelay provides 27 digital Memory Markers M1 ... M27 and 6 Analog Memory Markers AM1 ... AM6.

In your block configuration, you can assign a new number to the Memory Marker, provided this Memory Markersnumber does not already exist in your circuit program.

The output always carries the signal of the previous program cycle. This value does not change within the current program cycle.

Startup Memory Marker: M8

The M8 Memory Marker is set in the first cycle of the user program and can thus be used in your circuit program as a startup Memory Marker. It is reset after the first program execution cycle.

In the subsequent cycles, the M8 Memory Marker reacts in the same way as the M1 to M7 Memory Markers.

Backlight Memory Markers: M25 and M26

The M25 Memory Marker controls the backlight of the IDEC SmartRelay Display. The M26 Memory Markers controls the backlight of the Text Display (Text Display).

You can use the outputs of timers, message texts, or other function blocks to activate the backlight Memory Markers. To enable multiple conditions to control the backlight of the devices, you can use multiple function blocks in parallel or in sequence.

Message text character set Memory Marker: M27

The M27 Memory Marker, if used, determines whether the message texts of the primary character set or the secondary character set will display. You select the two character sets from either the Msg Config menu of IDEC SmartRelay or the File -> Message Text Settings menu command of WindLGC. Then when you configure message texts, you select whether a particular message text consists of characters from the primary character set (Character Set 1) or the secondary character set (Character Set 2).

In the circuit program, M27 can be used to enable the message texts of either the primary or secondary character set and to disable the message texts of the other. When M27=0 (low), then IDEC SmartRelay only displays the message texts from the primary character set. When M27=1 (high), then IDEC SmartRelay only displays the message texts from the secondary character set.

Analog Memory Markers: AM1 to AM6

You can use the Analog Memory Markers serve as a markers for analog inputs or analog instruction blocks. The Analog Memory Marker merely accepts an analog value as input and outputs that value.
