Backup
The Backup Object is used to copy recipe files (*.rcp), event files (*.evt), and data files (*.dtl) from the HMIs internal
memory to a USB flash drive, SD card, or a PC connected via Ethernet.
When Historical event log or Historical data log is selected, the historical event logs or data logs can be saved in their
native file formats (*.evt or *.dtl respectively) or in *.csv format. The range of history files can be selected and the
backup can be triggered by touch (Touch trigger mode) or by an external or internal bit (External trigger mode).
When External trigger (word) is selected for the Trigger Mode, the following registers control the Backup, allowing the
operator to define what files are backed up:
Trigger address: When the value changes from 0 to 1, the backup is triggered.
Trigger address + 1: Defines the start day for the backup.
Trigger address + 2: Defines the range of days to backup (maximum 90 days).
When the backup process starts, local bit LB9039 is set. When the backup is complete, local bit LB9039 is reset.
Timer
The Timer Object is used to control an output bit based on the state of an input bit and a measurement bit that is
controlled by a preset time. There are five different configurations or modes for the timer including On Delay, Off
Delay, Pulse, Accumulated On Delay, and Accumulated Off Delay.
When placed on a base window, the timer object is active only when that window is showing on the HMI. When
placed on the Common Window (Window 4), the timer object is active at all times, regardless of which window is
displayed on the HMI.
PLC Control
The PLC Control Object is used to perform a number of background tasks. Click the New button to set up a control
object. Click Type of control to open a drop-down box with the following options:
Change Window
This causes the HMI to close the currently-displayed Base Window, and display the Base Window whose number is in
the specified Trigger address.
The Change Window action occurs only when the HMI detects a change in the value of the specified Trigger Address.
After the window is changed, the HMI will write the number of the newly-displayed window to (Trigger Address +1).
Write data to PLC (current base window)
When the HMI initializes, and when the Base Window changes (for any reason), the number of the new Base Window
is written to the PLC Register specified by the Trigger address.
General PLC Control
Executes a data transfer of up to 32 words from the HMI to the PLC or from the PLC to the HMI when the value in the
Trigger Address is set to a valid operation code. After the operation is complete, the HMI sets the value in the Trigger
address to 0. A total of four values are needed to configure the General PLC Control attribute.
Address Function Details
Trigger address Operation code. Valid codes are 1, 2, 3, 4.
The Trigger address is set to 0 by the HMI
when the transfer is complete.
1. PLC to HMI: RW (recipe words)
2. PLC to HMI: LW (local words)
3. HMI to PLC: RW to PLC
4. HMI to PLC: LW to PLC
