Information about previous versions
Up to firmware version V1.0.3
Up to firmware version V1.0.3, data record communication between the SIWAREX WP231
and the SIMATIC CPU is not possible.
As of firmware version V1.0.4
As of firmware version V1.0.4 data records can be sent from the SIWAREX WP231 to the
S7-1200 CPU and received by the latter. This means that complete operation and
commissioning of the scales is possible via the SIMATIC CPU or the operator panel. The
current Ready-for-Use software must be used for this in addition to the matching FW. This
program contains the matching SIMATIC blocks and an extended WinCC configuration. You
can find the Ready-for-Use software in the configuration package or can be ordered from
product support: → Accessories (Page 175).
