Command group NetBit()
The NetBit command is an all-purpose tool to set or clear register bits of Jetter
products. The Jetter products are interconnected via an Ethernet network.
NetBit commands let you both set and clear bits in one go.
Simulating NetBit commands by means of NetCopy commands:
 A NetCopy command lets you copy the register value from the remote
node to the local controller.
 A NetCopy command lets you change the state of the bits on the local
controller as desired.

Another NetCopy command lets you copy the register value to the remote
node again.
For this, several commands are required. Thus, a register value may be
changed during this action by an application program running on the remote
controller. The second NetCopy command will then overwrite this value again.
There is an undefined data condition, which is prevented by the NetBit
functions.
Further advantages of NetBit commands as compared with the use of network
registers:

Within the command, you can directly specify any valid IP address.
 Within the command, you can directly specify any valid IP port.

The entire register address range of a remote node can be directly
addressed.
 The result of executing this command can be evaluated directly.
NetBit functions with the following nodes:
 Controllers
 Bus node
 Communication modules
To access other nodes, use the command NetBit as follows:
If ... ... then ...
you wish to set register bits for another
node,
use the command

NetBitSetReg
you wish to clear register bits of another
node,
use the command

NetBitClearReg
