Attributes Description
Process Process that handles the rack. 1 the plcprogram, 2 io_comm.
ThreadObject Thread object for the plc thread that should handle the rack. Only used if Process
is 1.
InvMask1 The invert mask states which channels are inverted. Handles channel 1-16.
InvMask2 See InvMask1. Handles channel 17 – 32.
FixedOutValue1 Bitmask for channel 1 to 16 when the I/O handling is emergency stopped.
Should normally be zero.
FixedOutValue2 See FixedOutValue1. FixedOutValue2 is a bitmask for channel 17 – 32.
ConvMask1 The conversion mask states which channels will be converted to signal values.
Handles channel 1 – 16.
ConvMask2 See ConvMask1. Handles channel 17 – 32.
Ssab_DO32KTS
The object configures a digital outputcard of type DO32KTS. The card has 32 output channels,
whose DoChan objects are internal attributes in the card object. The object is positioned as a child
to a Rack_SSAB or Ssab_RemoteRack object. Attributes, see BaseDoCard.
Ssab_DO32KTS_Stall
The object configures a digital outputcard of type DO32KTS Stall. The card is similar to
DO32KTS, but also contains a stall function, that resets the bus, i.e. all outputs are zeroed on all
cards, if no write or read i done on the card in 1.5 seconds.
Ai cards
All analog cards have a common baseclass, Ssab_BaseACard, that contains attributes that are
common for all analog cards. The objects for each card type are extended with channel objects for
the channels of the card.
