ControlNet Instruction Set
For detailed information about the instruction set for programming
PLC-5 processors, see the Enhanced and Ethernet PLC-5
Programmable Controllers User Manual, publication 1785-6.5.12,
and the PLC-5 Instruction Set Reference, publication 1785-6.1.
ControlNet I/O Transfer Instruction
Message Instructions on a ControlNet Network
Instruction Description
ControlNet I/O Transfer
CT
Status Bits
TO–Time-Out Bit
EW–Enabled-Waiting Bit
CO–Continuous Bit
ER–Error Bit
DN–Done Bit
ST–Start Bit
EN–Enable Bit
If the input conditions go from false to true, the data is
transferred according to the instruction parameters you set
when you enter the ControlNet I/O transfer instruction.
The Control Block (CT21:50) contains status and instruction
parameters.
You cannot use N (integer) control blocks on the
ControlNet network.
For continuous CIOs, condition the rung to be true for only
one scan.
