GOT-F900 SERIES (CONNECTION)
Communication Setting Specifications
The table below shows the transmission specifications available in the GOT-F900.
Set the transmission specifications in accordance with those in the microcomputer.
Flow control DSR/DTR or XON/XOFF
- For the GOT-F900 transmission specifications setting method, refer to section 14.7.
The data stored in the GOT-F900 is classified into word data (D) and bit data (M).
An address is assigned to each data, and each data is positioned as described below.
The microcomputer specifies data by "address". The screen creation software specifies data by "D" or "M".
1) Word data (D)
There are 4096 word devices (D0 to D4095). A serial number (address) is assigned to each of them.
There are 1,024 word devices (D0 to D1023) in the 24 V type F920GOT-K.
a) Word data (16 bits)
Each 8-bit word data is lined in the order of upper side (H) and lower side (L).
b) Double word data (32 bits)
Each 16-bit word data is lined from the higher address to the lower address.
When a 32-bit numeric value is displayed on the GOT-F900, if two word devices are located in the
reverse order, the correct value is not displayed because the most significant bit is regarded as
the sign (+ or -).
*1 "D****" shown in this chapter indicates a virtual device inside the GOT-F900, but does not indicate any
data register of the PLC.
