Modbus TCP/IP Client (Master)
 Offers 30 Client connections with up to 16 commands each to talk to multiple
servers
 Actively reads data from and writes data to Modbus TCP/IP devices, using
MBAP or Encapsulated Modbus message formats
 Transmits Modbus Function Codes 1, 2, 3, 4, 5, 6, 7, 15, and 16
 ControlLogix processor can be programmed to use special functions to
control the activity on the Client by actively selecting commands to execute
from the command list (Command Control) or by issuing commands directly
from the ladder logic (Event Commands)
5.1.3 Functional Specifications
 Modbus data types overlap in the module's memory database, so the same
data can be conveniently read or written as bit-level or register-level data.
 Configurable floating-point data movement is supported, including support for
Enron or Daniel
®
floating-point formats
 Special functions (Event Commands, Command Control, status, etc.) are
supported by message transfer (unscheduled) using the MSG instruction
 Configurable parameters for the Client including a minimum response delay
of 0 to 65535 ms and floating-point support
 Supports up to 30 Clients with up to 16 commands for each Client
 Error codes, counters, and module status available from module memory
through the servers, through the Clients, or through the ladder logic and
controller tags in RSLogix 5000
