3	DWORD	PLC->VK	Alarm bits. Program should go to STOP mode: Bit 0..31 : Alarm indication
4	DWORD	PLC->VK	Warning bits. Program continue in AUTO mode: Bit 0..31 : Warning indication

2. Commands to hoist

2.1 Check <Ready state>

In order to send a new command to hoist, VKQV will check the following conditions :

1. Hoist mode is in Auto ( Reg2 Bit 0-2 == 4)

2. Hoist is ready to accept new command ( Reg2 Bit 3 == ON)

3. Hoist has no blocking alarm activated (Reg2 Bit 4 == OFF)

4. Command trigger = status trigger (Reg0 Bit 15 == Reg2 Bit 15)

If all of those conditions are verified than a new command can be send.

2.2 Sending a new command

VKQV writes a new command in the register #0. In this new command, the Bit15 will be inverted from its last value, telling to the PLC that a new command has been written.

When the PLC see that Reg0 Bit15 is different than Reg2 Bit15, it knows that a new command is pending. The Reg2 Bit4 should go Off telling to VKQV that the command is being executed. When the command is terminated (hoist is in destination), Reg2 Bit4 should go ON again and Reg2 Bit15 must be set with the content of Reg0 Bit15.

2.3 Move horizontal command

A move horizontal command is specified by writting the value 1 in the Reg0 HoistCommand bits. The Reg0 Bit4 is set to ON if the next movement is a vertical lift. This is used by the PLC to activate some equipement command ( open tank cover, or turn on spray, or etc…). The Reg0 Bit5 is set to ON when the horizontal movement is done without rack holder (jig) on the hoist. This is also an information used by the PLC to not activate some equipement command because the hoist is empty. The destination logical position is written in Reg0 Bit7-14. This is corresponding to the horizontal destination of the hoist. The Reg0 Bit15 is inverted from its previous state. And the Reg0 Bit 17 is set to ON telling to the PLC that VKQV program mode is in AUTO (set to OFF if the program mode is in STOP. This is corresponding in a command done by the remote control of the hoist).

Example of horizontal command:

Hoist is located in logical position #16 in lower vertical position:

Move to logical position #3, program mode = STOP, there is no rack holder on the hoist:

Command is accepted by the PLC:

Hoist is moving horizontally and is actually in logical position #9:

Hoist is in the logicial position 3 and is ready to accept a new command:

2.4 Move vertical command

A move vertical command is specified by writting 2 in the Reg0 HoistCommand bits. The Reg0 Bit5 is set to ON when the movement is done without rack holder (jig) on the hoist. The type of vertical movement is specified in the Reg0 Bit8-11 (1=go up to top, 2=go down to bottom, 3=go up to intermediate high, 4= go up to top from the intermediate high, 5=go down to bottom from the intermediate high, 6=go down from top to intermediate high, 7=go up to HLiftout, 8=go up from HLiftout to top, 9= go down from top to HLiftout, 10= do down from HLiftout to bottom). The speed to be use is specified in the Reg0 Bit12-14 (0..7).

Example of vertical command:

Hoist is in the logicial position #3 in lower vertical position:

Move to top:

Command is accepted by the PLC:

Hoist is moving vertically. It is in logical position #3 and is clipped:

Hoist is in logical position #3 in upper vertical position and is ready to accept a new command:

2.5 Hoist agitation command

A hoist agitation command is specified in writting 4 in the Reg0 HoistCommand bits. This command tells to the hoist controller to agitate a load. The hoist must be in lower position and centered. When the controller receive this command, it starts to agitate while a time defined in the controller. It must stop in lower position. While the hoist is agitating, the bit22 of status register is set by the controller. QuickView will not pick/drop load while this bit is activated.
