3) Data register (D)
A data register consists of the block No. and the device No. as shown below.
D
¡¡¡¡¨¨¨¨¨
•In "
¡¡¡¡
", specify the block No. (shown in Table 1 in the previous page) of the data
register in a decimal number in four digits.
•In "
¨¨¨¨¨
", specify the device No. (shown in Table 1 in the previous page) of the data
register in a decimal even number in five digits.
Example: When specifying "D102031004"
Device symbol = D
Block No. = 1020
Device No. = 31004
• Supplement
- As to data registers, define the data block using the STEP7 in advance for the CPU, and
download it to the CPU.
- As to input and output relays, the English (IEC) notation is used in the GOT. However,
when the German (SIMATIC) notation is selected in the STEP7, devices E, A and Z are
equivalent to I, Q and C respectively.
- Because the F900 Series GOT does not distinguish the CPU type in the S7-300/400
Series PLC, the device range is checked inside the range shown in Table 1 in the previ-
ous page.
("STEP7" is the name of the programming software for the S7-300/400 Series PLC.)
• Restraint on device specification
- Word specification for bit devices and bit specification for word devices are not supported
in the F930GOT-E in the same way as connection to another PLC.
