- 28 -
(e) “- / -” : Module without input/output
(Same as when MODULE LENGTH = 1 and
MODULE = 00)
(f) “OVR” : DI SIZE + DO SIZE exceeds 244 bytes.
(g) “ERR” : The data assigned to "MODULE =" does not
adhere to the PROFIBUS specification.
Setting item
Item Description
Set the first addresses of DI and DO. DI ADDR
DO ADDR
Setting range : See CAUTION below.
Set the sizes of DI data and DO data. DI SIZ
DO SIZ
Setting range : 0 to 244 (bytes)
CAUTION
When assigning addresses, keep the following in
mind.
(1) When setting the PMC area, note the following:
The R address or E address can be set.
For a multi-path PMC, enter an PMC address
as follows:
<Path number>:<PMC address>
For R0500 for the second PMC path, for
example, enter "2:R500". When only a PMC
address (R500) is entered, it is assumed to be
the PMC address for the first path (1:R0500).
If the ":" key is not provided, the "/" or "EOB"
key can be used instead.
(2) The DI data area, DO data area, diagnostic
data area, and operation mode display area
cannot overlap each other.
(3) The area assignment area and the area used
by the ladder program cannot overlap each
other.
NOTE
The maximum DI/DO transfer size per slave station
is 244 bytes in all of DI/DO.
6 Press soft key [(OPRT)] as needed and then use the following
soft keys.
[PREVI SLAVE], [NEXT SLAVE] :
Pressing soft key [PREVI SLAVE] moves the cursor to the
first slot of the previous slave station. Pressing [NEXT
SLAVE] moves the cursor to the first slot of the next slave
station. Pressing soft key [PREVI SLAVE] or [NEXT
SLAVE] after entering a station number moves the cursor to
the first slot of the specified station number.
