西门子控制面板TP177BPN/D

触控型和键控型前面板设计在 Panel PC 的前端。本产品的特点是组合了触控型和键控型操作，耐润滑油。

装饰膜通过显示器的触控区域完全分层，增强了抗污染和焊缝的能力，无镶边和接缝，便于清洗。由于表面材料相同，开口和开孔可完全忽略，因此可用在使用润滑油和类似冷却液和润滑剂的环境中。

可使用触控笔进行清洁，触控笔作为标准产品供货，可存储在前支架 因此使用触控笔时不必顾及脏手或油手。触控笔人性化设计，适宜用于带手套时，使用弹性螺旋电缆连接至前端。 存放在前端的专用不锈钢支架上，可随时使用。

User logon procedure using the SIMATIC Logon Service.

SIMATIC Logon can be used to configure the associated roles andfunctional authorizations (role management) for a SIMATICapplication. This configuration is stored in the database of theSIMATIC application.

SIMATIC Logon performs Windows user authentication duringapplication runtime; the procedure is as follows:

• When prompted by a SIMATIC application (1), the SIMATIC LogonService opens a logon dialog (2). The user enters his or her name,password and domain. The logon data are sent to the useradministration of the operating system (3), which then reports theauthentication attempt event to the logon service (4).

• The logon service records all events in an event log (5), forexample successful logon, failed logon attempts, logoff by theuser, automatic logoff and password change.

• If authentication is successful, the SIMATIC Logon Service sendsthis information, including the Windows group membership, to theSIMATIC application (6), which maps the roles and associatedfunctional rights within the application (7).

The electronic signature means that operations cannot be performeduntil enabled by a previously authorized user. Authorization isassigned in the application by associating the users grouped atoperating system level with the group with the operations.

Note:

At the moment this function is implemented as a system functiononly on SIMATIC BATCH. The electronic signature can, however, alsobe flexibly implemented for specific applications.

The Development Kit uses an example to show the programmer how toembed SIMATIC Logon into a customer application.
