Modbus TCP/IP Specific Registers
(Only for use with the CM090 Modbus TCP/IP option card)
 The Modbus TCP/IP Option Card CM090 differs slightly from Modbus RTU in its register structure. The CM090 card has a different
set of Command registers and additional monitor registers. However, all Monitor and Parameter registers listed earlier in this chapter
can also be accessed over Modbus TCP/IP. Other Modbus TCP/IP protocol specific items include:
 A maximum of 10 simultaneous connections are allowed.
 The Run Command and Frequency Reference may only be accessed through UNIT ID 1. While the drive is in remote RUN mode, the
Run command must be continually refreshed within the Timeout setting in the configuration webpage. This can be set from 100 ms to
30 sec. If the Run command is not refreshed within the set time, an EF0 fault will occur. Refer to the appropriate drive manual for
information on EF0 and setting the appropriate drive response. If a UNIT ID 1 connection is active, the NS/CON LED will blink at
approximately a 500 ms cycle.
 The TCP/IP connection must be refreshed within 60 seconds. If it is not refreshed within 60 seconds, the connection will be closed.
 This implementation of Modbus TCP/IP supports Modbus functions 3 (read multiple registers), 6 (write single register) and 16 (write
multiple registers).
