• Common Relay Information(2032)

Bit 0

Reserved

Bit 1

After a screen (Base, Window) changes, turns ON until the Part handling is complete.

Bit 2

Reserved

Bit 3

Turns ON while the initial screen displays at power ON.

Bit 4

Normally ON.

Bit 5

Normally OFF.

Bit 6

Turns ON when backup memory (SRAM) data is erased. Only onboard backup memory (SRAM)

Bit 7

When using D-Scripts, turns ON when a BCD error occurs.

Bit 8

When using D-Scripts, turns ON when a zero error occurs.

Bit 9

Turns ON when a recipe could not be transferred to backup memory (SRAM).

Bit 10

Turns ON when filing data transfer initiated by the Control Word Address could not transfer from PLC to SRAM. Also, when transferring from a PLC by way of a Special Data Display (filing), and when using the Transfer Complete Bit Address, it turns ON when data could not transfer between PLC -> Internal Device, or PLC -> SRAM.

Bit 11

Turns ON during transfer between SRAM <-> Internal Device by means of a Special Data Display (Filing).

Bit 12

When using D-Scripts, turns ON when a communication error occurs from a memcpy ( ) or address offset designation read. Turns OFF when data finishes reading normally.

Bit 13

In the [System Settings] [Script I/O] page, when no [D-Script/Global D-Script] is set in the project, turns ON when the readout of the Send function, Receive function, Control, Status variable, and Received Data Size is executed in [SIO Port Operation]'s Label Settings.

Bit 14

In the [System Settings] [Script I/O] page, when [D-Script/Global D-Script] is set in the project, turns ON when an extended script's [Text Operation] function is executed. Also, in the [System Settings] [Script I/O] page, when [Extended Script] is set in the project, turns ON even when a D-Script/Global D-Script [SIO Port Operation]'s I/O function (IO_WRITE, IO_READ) is executed.

Bit 15

Reserved

• Base Screen Information (2033)

Bit 0

Reserved

Bit 1

After a Base screen changes, turns ON until the Part handling is complete.

Bit 2 to 15

Reserved

• Reserved (2034, 2037, 2040 to 2047)

Values are undefined in reserved addresses. Do not use.

• 1-Second Binary Counter (2035)

Increments once every second immediately after the power is turned ON. Data is in Bin format.

• Display Scan Time (2036)

The display time starts from the first Part set on the display screen to the end of the last Part. Data is stored in Bin format, in millisecond units. The data is updated when the targeted Parts' pre-processing completes. The data's initial value is "0".
There is an error of +/-10 ms.

• Display Scan Counter (2038)

The counter increments each time the Part set on the display screen processes. Data is in Bin format.
