CIP Symbolic Addressing
Users may access any global variable through CIP Symbolic addressing except for
system and reserved variables.
One- or two-dimension arrays for simple data types are supported (for example,
ARRAY OF INT[1..10, 1..10]) are supported but arrays of arrays (for example,
ARRAY OF ARRAY) are not supported. Array of strings are also supported.
CIP Client Messaging
CIP Generic and CIP Symbolic messages are supported on Micro800 controllers
through the Ethernet and serial ports. These client messaging features are enabled
by the MSG_CIPSYMBOLIC and MSG_CIPGENERIC function blocks.
See Micro800 Programmable Controllers: Getting Started with CIP Client
Messaging, publication 2080-QS002 , for more information and sample
quickstart projects to help you use the CIP Client Messaging feature.
Supported Data Types in CIP Symbolic
