Use the Í or Ú cursor buttons to select the NET-ID you want (NET-ID 7 in this
example).
Click on OK.
The local I.., or Q.. operand has been changed to a NET operand nI.., nR.., nQ.. and
nS...
Several NET stations with their own circuit diagram
The relevant NET stations each process a circuit diagram.
l
Every station has read access to all inputs and outputs of the other stations.
l
The station only has write access to its local outputs and outputs of its local
expansion unit.
Example: Station 1 uses the state of Q1 of station 2 in its circuit diagram. Station 1,
however, cannot set Q1 of station 2 to 1.
l
Send NET (SN) and Receive NET( RN) is used for exchanging bits. These oper-
ands are always used in pairs.
l
Put (PT) and Get (GT) are used in order to exchange double word operands via
the NET.
