Description

Function description

This function block allows the entry of the TCP/ IP address for function blocks READ_REG, CREAD_REG, WRITE_REG and CWRITE_REG. The address is transferred as a data structure.

EN and ENO can be configured as additional parameters.

NOTE: You must be familiar with your network when programming the TCP_IP_ADDR function block. A complete description of the TCP/IP routing is provided in the Quantum using EcoStruxure™ Control Expert, TCP/IP Configuration, User Manual.

Parameter description

Description of input parameters:

Parameters	Data type	Description
`MAP_IDX`	`BYTE`	Map index MBP on Ethernet Transporter (MET) mapping index
`Slot_ID`	`BYTE`	Slot ID Slot of the NOE module
`IP_B4`	`BYTE`	Byte 4 (MSB) of the 32-bit destination IP address
`IP_B3`	`BYTE`	Byte 3 of the 32-bit destination IP address
`IP_B`2	`BYTE`	Byte 2 of the 32-bit destination IP address
`IP_B1`	`BYTE`	Byte 1 (LSB) of the 32-bit destination IP address

NOTE: For the Slot_ID parameter: when using an integrated Ethernet CPU module such as the 140 CPU 651 •0, the slot ID must be 254 (FE hex) regardless of the CPU slot.

Parameters	Data type	Description
`ADDRFLD`	`WordArr5`	Data structure used to transfer the TCP/IP address
