As soon as one of the following rules applies, the maximum configuration has been reached.
Maximum mechanical configuration
Backplane bus length: Maximum 1 m mounting width (without CPU 1515SP PC2, including
server module)
Electrical maximum configuration
The number of operable I/O modules of a potential group is limited by the
● Power consumption of the I/O modules
● Power consumption of the components supplied via these I/O modules
The maximum current-carrying capability of the terminals on the BaseUnit L+/ground is 10 A.
When using the CPU 1515SP PC2 with the maximum configuration, the USB load must also
be considered:
● Horizontal mounting
– Ambient temperature of 0 to 60 °C with maximum 32 I/O modules
4 x low-current
(500 mA) USB load
– Ambient temperature of 0 to 55 °C with maximum 64 I/O modules
2 x high-current
(900 mA) + 2 x low-current (500 mA) USB load
● Vertical mounting
– Ambient temperature of 0 to 50 °C with maximum 32 I/O modules
4 x low-current
(500 mA) USB load
The address space is predefined. However, you can adjust the address space in the user
program.
