STEP 7 Professional 2010 现已可供货，立即生效。此版本的 STEP 7 Professional 合并了新的 STEP 7 V5.5。用户可以通过订购升级包(6ES7810-5CC11-0YE5)将以前版本的 STEP 7 Professional 升级到当前版本。具有 STEP 7 Professional 最新软件更新服务协议的用户将会自动接收到升级包，用于升级到 STEP 7 Professional 2010。

STEP 7 Professional 软件包提供了全部五种 IEC 61131-3 标准化编程语言：

指令表 (STL)

梯形图 (LAD)

函数块图(FBD)

结构化文本(S7-SCL)

顺序功能图表 (S7-GRAPH)

此外，还可以离线测试应用程序，即直接在 PC/PG 上无需连接 PLC、使用 STEP 7 Professional中包含的仿真软件进行测试，所有语言都可以混合使用。例如，可以在梯形图中调用使用 S7-SCL 编制的标准功能。

为了可以在调试之前检测到编程错误，STEP 7 Professional 还包含了离线测试 - 这与所选的编程语言无关。

STEP 7 Professional 使许可证管理和软件维护都变得非常方便。通过框架安装，可以“一次性”安装或更新所有 Professional 组件。而软件更新服务则使得用户更加容易获得所有功能增强，无论是 Professional 升级包还是补丁包。

使用 STEP 7 Professional 的优势：

● 降低了创建程序所需的时间

● 文档制作更加容易和清晰

● 及早发现编程错误

● 改进了调试和维修阶段的用户支持

● 许可证管理和版本维护更容易

● 相比单个产品安装，框架式安装使安装更容易

● 与集成的各产品的单价总和相比，成本更低
