Exchange Of Modules; Ac500-S Restart Behavior; Replacing Ac500-S Safety Plc Components; Environmentally Friendly Disposal - ABB AC500-S Safety User Manual

● The general safety regulations and applicable national safety regulations shall be strictly
observed.
● The electrical installation shall be carried out in accordance with relevant regulations.
● Take the necessary protective measures against static discharge.

2.8 Exchange of modules

SM560-S / SM560-S-FD-1 / SM560-S-FD-4 safety CPU automatically detects an exchange of
safety I/O modules during the system start-up. The overall system (safety CPU and PROFIsafe
features of unique addresses for safety devices
ensure that exchanged safety modules are operated with correct parameters and incompatible
module types are rejected. No unsafe state is possible if wrong safety I/O module type is put on
the given terminal unit TU582-S.

2.9 AC500-S restart behavior

When SM560-S / SM560-S-FD-1 / SM560-S-FD-4 safety CPU is restarted using powering
off/on, the previously saved error information is lost. The safety I/O modules receive their
parameter sets each time during system start-up. The safety CPU is able to reintegrate safety
I/O modules using PROFIsafe start-up behavior
automatic start-up after powering off/on, you must program a restart protection in the safety pro-
gram. The safety process data outputs must be blocked until manually acknowledged. These
safety outputs must not be enabled until it is safe to do so and faults were corrected.

Replacing AC500-S safety PLC components

When replacing software components on your programming device or PC with a newer version,
you must observe the notes regarding upward and downward compatibility in the documentation
and readme files for these products.
Hardware components for AC500-S (safety CPU and safety I/Os) are replaced in the same way
as in a non-safety AC500 automation system.
2.11

Environmentally friendly disposal

All AC500-S safety components from ABB are designed with a minimal environment pollution
effect. To enable environmentally friendly disposal of AC500-S safety components, they can be
partially disassembled to separate various components from each other. Disposal of those
materials shall be done in accordance with applicable national and international laws.
2.12

Safe communication

Safety data are transferred between safety CPU and safety I/Os using PROFIsafe profile
SM560-S / SM560-S-FD-1 / SM560-S-FD-4 safety CPU needs a non-safety CPU to communi-
cate to safety I/O modules. All safety-related communication takes place through the non-safety
CPU using a "black channel" principle of data transmission
The communication of safety CPU to remote safety I/O modules is done using PROFINET IO
field bus with a PROFIsafe profile for safe data transmission
modules can be mixed on a local I/O bus both in central and remote configuration. PROFINET
IO controller communication module (CM579-PNIO) shall be used on non-safety CPUs as a part
of the "black channel" to transfer safety data to PROFINET IO devices. PROFINET devices
CI501, CI502, CI504 and CI506 can be used to attach safety I/O modules in remote configura-
tions.
