同时，国际自动化学会（ISA）已获得了已延长的美国国家标准研究所（ANSI）批准ISA100.11A标准 - Wirelesshart的“竞争”标准。言论在“无线战争”和融合变得严重的道路上死亡真是太好了（请参阅Renee Robbins Bassett的文章Automation World).
ANSI批准通常是例行事项，但是ISA 100无线委员会具有巨大的争议。真是太糟糕了，一位ISA领导人告诉我，这是他在此过程中某个时候看到的最不适当的委员会。当采用原始ISA100.11A时，该委员会的几名成员认为未观察到适当的程序并请愿ANSI拒绝批准。实际上，ANSI确实拒绝了批准，并且该问题返回委员会进行进一步工作。
Much as I thought at the time, this is almost an anti-climax. Many companies have WirelessHart devices in the market, while ISA100 products are still in development (although a few that meet the requirements without final approval are released) by a few companies.
