●
If you use long synchronization lines, you have to extend the monitoring time of the
connection at an H-CPU V6.0, see chapter Communication via fault-tolerant S7
●
The startup time of the CPU at power on, the loading time of blocks, as well mas the
startup after a plant modification at runtime can be significantly prolonged by encrypted
blocks; see chapter Encrypting blocks (Page 79).
●
The following applies to PROFINET in the fault-tolerant system: The job must be
repeated if it is rejected with return value W#16#80BA when using SFB 52/53/54.
Basic knowledge required
This manual requires general knowledge of automation engineering.
Moreover, it is assumed that the readership has sufficient knowledge of computers or
equipment similar to a PC, such as programming devices, running under the Windows XP,
Windows Vista or Windows 7 operating system. An S7-400H is configured using the STEP 7
basic software, and you should thus be familiar in the handling of this basic software. This
knowledge is provided in the
Programming with STEP 7 manual.
In particular when operating an S7-400H system in potentially explosive atmospheres, you
should always observe the information on the safety of electronic control systems provided in
the appendix of the
S7-400 Automation System, Installation manual.
