Ansi B11 - Siemens SINAMICS V90 Operating Instructions Manual

Safety Integrated function
8.1 Standards and regulations
1. Control systems that contain software-based controllers must:
● In the event of a single fault
– cause the system to switch to a safe shutdown mode
– prevent the system from restarting until the fault has been rectified
– prevent an unexpected restart
● Offer the same level of protection as hard-wired controllers
● Be implemented in accordance with a recognized standard that defines the requirements
for such systems.
2. IEC 61508, IEC 62061, ISO 13849-1, ISO 13849 2 and IEC 61800-5-2 are specified as
suitable standards in a note.
Underwriter Laboratories Inc. (UL) has defined a special category for "Programmable Safety
Controllers" for implementing this requirement (code NRGF). This category covers control
devices that contain software and are designed for use in safety-related functions.
A precise description of the category and a list of devices that fulfill this requirement can be
found on the Internet at the following address:

for category "NRGF"
TUV Rheinland of North America, Inc. is also an NRTL for these applications.
8.1.3.4

ANSI B11

ANSI B11 standards are joint standards developed by associations such as the Association
for Manufacturing Technology (AMT) and the Robotic Industries Association (RIA).
The hazards of a machine are evaluated by means of a risk analysis/assessment. The risk
analysis is an important requirement in accordance with NFPA 79, ANSI/RIA 15.06, ANSI
B11.TR-3 and SEMI S10 (semiconductors). The documented findings of a risk analysis can
be used to select a suitable safety system based on the safety class of the application in
question.
The situation in Japan is different from that in Europe and the US. Legislation such as that
prescribed in Europe does not exist. Similarly, product liability does not play such an
important role as it does in the US.
Instead of legal requirements to apply standards have been defined, an administrative
recommendation to apply JIS (Japanese Industrial Standard) is in place: Japan bases its
approach on the European concept and uses basic standards as national standards (see
table).
