RSNetworx
Network manager software (Catalog No. 9357-DNETL3). Similar to
DeviceNet Manager software.
Server
The device that responds to a message from a client device. The Server’s
response may cause it to return a message to the client. Applies to both
Explicit messaging and I/O connections. With Explicit Server messaging,
the PanelView terminal is the server device that responds to information
requests from client devices. See Client.
Strobe
Messaging that involves an output message broadcast by the master to all
slaves configured for this type of messaging. Each slave responds with an
input message. The output message has one bit of data for each slave. The
input message is from 0 to 8 bytes long. Also known as Bit-Strobe. The
PanelView does not support this type of messaging.
UCMM
Acronym for Unconnected Message Manager. The UCMM provides for the
dynamic establishment of Explicit Messaging Connections. Many simple
devices do not have UCMM capabilities and may be referred to as group 2
only server devices.
