Citect for DOS uses a protocol dependent
method for packing bits into memory. So each protocol may use a
different packing order. Citect for Windows uses a generic method
for packing digital bits into memory. All protocol drivers convert
the digital bits into the same packing order. So when Citect for
Windows communicates to Citect for DOS it must will swap the
digitalis bits around for some of the protocols. Citect for Windows
only swaps the bits around for the protocols it knows about. These
are TIWAY, MODBUS and MBPLUS. The TITCPIP protocol was released
after Citect for DOS and was not supported. You may however support
the TITCPIP protocol in Citect for DOS by setting the protocol to
TIWAY and then setting the following parameters:
[CitectForDos]
SwapBits=1
SwapBytes=1
These parameters tell Citect for Windows to swap the bits and
bytes around for all protocols to be sent to Citect for DOS.
Support for the TITCPIP protocol will be added in Citect for
Windows version 5.0.
