Maximum Consistent Data Lengths In Bytes For Im 308-C As Dp Master - Siemens SIMATIC S5 Manual

Data consistency, The table below shows the maximum data lengths at which data consistency
IM 308-C as DP is ensured. The length is automatically taken into account in parameterization
master with COM ET 200 Windows.
244 bytes outputs (DP slave inputs) is the maximum if all the outputs are dig-
ital with byte consistency over module. For all other cases, see Table 3-5 (bus
profile = PROFIBUS-DP).
