15.4 Device Range that Can Be Set
(b) S7-200 Series
POINTPOINTPOINT
Device settings of SIEMENS PLC (S7-200 series)
(1) When setting bit devices (except Timer and
Counter)
Set the device using the byte address (DEC) and
the bit address (0 to 7).
(c) SIEMENS OP (Ethernet)
POINTPOINTPOINT
Device settings of SIEMENS PLC (S7-200/300/400/
1200 series, SIEMENS OP (Ethernet))
(1) When setting a bit device as a bit device
Set the device using the format of byte address
(DEC) + bit address (0 to 7).
(2) When setting a data register
Set the device using the format of data block
(DB) + data word (DW).
(3) Precautions when setting devices
(a) Preparing to set a data register
It is necessary to define the data block using a
peripheral software and sequence program,
before using a data register. Setting more
than one data block cannot be done for the
data register.
(b) Object that cannot be set Timer (current
value) (T)
Only one device can be set for the write target
of this device. Therefore, multiple devices,
such as, using the recipe function, etc.,
cannot be used.
(c) Notation method of the data registers with the
bit specification
The notation of the data registers with the bit
specification differs between the GOT and the
PLC. The following shows the
correspondence table.
