the associated control transfer requests. A value of 0 prevents the associated control transfer requests.
Therefore, if the ArmorStart device is running at the time of a program-to-operator control transition, the
ArmorStart device continues to run at the most recent commanded Program Speed. If a different
program-to-operator control transition is desired, then the status of the ArmorStart device and the operator
command requests must be monitored and the appropriate program commands must be issued before the
Xxxx.Cmd_ProgToOperPermissive is allowed. Therefore, it is very important that the status of the
ArmorStart device is monitored and appropriate program commands, for the specific application, are issued
before the Xxxx.Cmd_ProgToOperPermissive tag is set. This makes sure that a safe program-to-operator
control transfer is executed.
In addition, there is no logic within the Add-On Instruction that sets the Set_SpeedProg upon transfer to
Program mode, so the ArmorStart device assumes the last commanded Set_SpeedProg speed value unless
logic is programmed outside of the Add-On Instruction to set it to a different value. Therefore, it is very
important that the status of the ArmorStart device is monitored and appropriate Program commands, for the
specific application, are issued before the Xxxx.Cmd_OperToProgramPermissive tag is set. This makes sure
that a safe operator-to-program control transfer is executed.
ATTENTION
If an Xxxx.Cmd_ProgToOperPermissive tag is set to 1, the associated Add-On Instruction is programmed to
allow a transfer from Program Control to Operator Control regardless of the current direction, speed, or
active status of the ArmorStart device. In addition, the AOI is programmed to transfer the current Program
Speed value Xxxx.Set_SpeedProg to the associated Operator Speed tag, Xxxx.Set_SpeedOper, creating a
bumpless transfer when a transfer from Program Control to Operator Control is executed.
ATTENTION
If an Xxxx.Cmd_OperToProgramPermissive tag is set to 1, the associated AOI is programmed to allow a
transfer from Operator Control to Program Control regardless of the current direction, speed, or active
status of the ArmorStart device.
ATTENTION
If the ArmorStart device is started in Operator Mode and the FactoryTalk View ME ArmorStart Faceplate is
closed while the ArmorStart device is running, the ArmorStart device will continue running at the current
Set_SpeedOper tag value.
It is critical to understand how this operation affects the specific application and appropriate actions and
safeguards are implemented.
ATTENTION
There is no logic within the AOI that controls the minimum or maximum ArmorStart Commanded Speed
values sent to the specific drive.
It is important to understand the limitations of the motor connected to the specific drive and set the
appropriate ArmorStart device parameters and add additional Program logic if necessary.
