Forcing the virtual input data
Requests may be placed for the 24 virtual input data and table data via a web server inte-
grated within the PNOZ mc10p (enter IP address of the PNOZ mc10p in Internet Explorer)
(Bits 24 to 128 can be read and written using Table 9 Segment 1). The 20 Bytes (I/O and
table data from the PNOZmulti) are uploaded accordingly. The web server can only be
used in NRT status and not in the sercos III communication phases.
Communication with the sercos III Master
The input/output data is transmitted synchronously. The slow data stored in the object buff-
er is read asynchronously.
Synchronous data exchange
Default configuration for synchronous data exchange:

To reduce data traffic, only the first 4 Bytes can be configured (see S-0-1507.0.2 in the
chapter entitled
Description of IDNs [ 73] ). Then only the 24Bit virtual I/Os / LED sta-
tus are downloaded from the PNOZmulti.
