Variable Type Use
SYS_DEVTYPE_ERR DEVTYPE_ERR_
TYPE This variable indicates erroneous devices in the system
per device type category.
The DEVTYPE_ERR_TYPE is a structure containing a
BOOL flag for each type of device, plus TC and Servo,
that can be included in PowerMACS system:

ANYTYPE : True if a device of any type is erroneous
in the system.

TC : True if not all TCs have communication contact
with all the other TCs in the system.

SERVO : True if any servo in the system is erroneous.

PLC : True if any PLC reporter device in the system is
erroneous.

FIELDBUS : True if any fieldbus device in the system
is erroneous.

IO : True if any I/O device in the system is erroneous.

EXTCOM : True if any external communication device
in the system is erroneous.

API : True if any API device in the system is
erroneous.

IDDEV : True if any ID device device in the system is
erroneous.

PRINTER : True if any TC printer device in the system
is erroneous.

TOOLSNET : True if any ToolsNet device in the
system is erroneous.
STN_DEVTYPE_ERR DEVTYPE_ERR_
TYPE This variable indicates erroneous devices related to the
station per device type category.
It functions the same ways as the SYS_DEVTYPE_ERR
variable with the differences that only the devices
connected to a TC that belongs to this station are
checked.
Note: There is one exception to the above rule. The flag
TC is set True also if this station has lost communication
contact with the System TC (TC1).
DEVICE_ERR DEVICENO_ERR_
ARR This variable indicates erroneous devices in the system
per device number.
The variable is an array of BOOL where each element
represents the device with the number equal to the array
index number.
That is, if DEVICE_ERR[10] is True then the device with
device number 10 is erroneous.
