1.5 Terminal units (AC500 standard)
Hot swap
System requirements for hot swapping of I/O modules:
– Types of terminal units that support hot swapping of I/O modules have the
appendix TU5xx-H.
– I/O modules as of index F0.
The following I/O bus masters support hot swapping of attached I/O modules:
– Communication interface modules CI5xx as of index F0.
– Processor modules PM56xx-2ETH with firmware version as of V3.2.0.
NOTICE!
Risk of damage to I/O modules!
Hot swapping is only allowed for I/O modules.
Processor modules and communication interface modules must not be removed
or inserted during operation.
Conditions for hot swapping
– Digital outputs are not under load.
– Input/output voltages above safety extra low voltage/
protective extra low voltages (SELV/PELV) are switched off.
– Modules are completely plugged on the terminal unit with both snap fit
engaged before switching on loads or input/output voltage.
