The input address
Data written from TD7onTIM to the MODBUS slaves is read from the input address area of
the CPU. Only the specified address areas can be read by TD7onTIM. Data from other
areas, for example analog values acquired over peripheral input words (PIW) must be
mapped to the bit memory or data block area by the user program.

S7 CPU input address
• DB: Data block
• Memory bit: Memory bit area
• Input: Process input image (PII)
By specifying the data type, you specify the data type with which the data is
transferred from the S7 CPU to the MODBUS slaves. The drop-down list
offers the following data types for the three memory areas:
BOOL, BYTE, CHAR, WORD, DWORD, INT, DINT, REAL
Number of double words included in the array (maximum 100).
Specifies the DB number in the CPU if the data block memory area (DB) was
selected
involving more than one byte (WORD, DWORD), the least significant byte
number must be entered as in STEP 7.
MODBUS output
Specifies the register address.
You will find the permitted address ranges in the documentation of your MODBUS
slave.
