S7 CPU output address
Data read from the MODBUS slaves by TD7onTIM is saved in the output address area of the
CPU. Only the specified address areas can be written by TD7onTIM. Data for other areas,
for example analog values output via peripheral output words (PQW) must be mapped via
the bit memory or data block area by the user program.
Name: Output address
Memory area: The following options are available for the destination address:
• DB: Data block
•
Memory bit: Memory bit area
• Output: Process output image (PIQ)
Data type: By specifying the data type, you specify the data type with which the data is
transferred from the MODBUS slaves to the S7 CPU. The drop-down list
offers the following data types for the three memory areas:
BOOL, BYTE, CHAR, WORD, DWORD, INT, DINT, REAL
DB No.: Specifies the DB number in the CPU if the data block memory area (DB) was
selected
Address [Byte]: Input field for the byte number in the selected memory area. For data types
involving more than 1 byte (WORD, DWORD, ...), the least significant byte
number must be entered as in STEP 7.
Number: Number of double words included in the array (maximum 100).
MODBUS read status
The result of a read job is returned by the MODBUS slave in an acknowledgement message.
The result is returned as a hexadecimal word and can be saved as a status in the output
area of the CPU.
Name: MODBUS read status
Memory area: The following options are available for the address range of the S7 CPU:
• DB: Data block
•
Memory bit: Memory bit area
• Input: Process input image (PII)
DB No.: Specifies the DB number in the CPU if the "data block" memory area (DB)
was selected
Address [Byte]: Input field for the byte number in the selected memory area.
