Main Differences between the S7-400 and the S7-300

Larger memory and more I/Q/M/T/C

Addresses of input/output modules selectable Can connect EUs from S5 and use S5 CP/IP modules

More system functions, such as programmed block communication

Block size up to 64KB and twice as many DBs

Complete restart and restart

Setpoint/actual comparison of configuration on startup

Modules can be removed without disconnecting the power supply

Several part process images

Priorities of OBs are parameter-assignable

Several OBs for cyclic, hardware and time-of-day interrupts

Block nesting up to 16 levels

Size of L Stack selectable for each execution level

4 accumulators

Multicomputimg
