12.5 Using a CP module to access Web pages

For local access through a local wireless access point, enter the IP address of the S7-1200

CPU or a Web server-enabled CP (Page 1010) in the local rack:

● http://ww.xx.yy.zz or https::/ww.xx.yy.zz to access the standard Web pages (Page 1011)

● http://ww.xx.yy.zz/basic or https::/ww.xx.yy.zz/basic to access the basic Web pages

For increased security, configure the Web server to be accessible only by secure access

(HTTPS) (Page 1003).

Using a CP module to access Web pages

Regardless of whether you access the Web server from a PC or a mobile device, you can

connect to standard Web pages through one of the following CP modules when you have

configured it in STEP 7 and installed it in the local rack with the S7-1200 CPU:

● CP 1242-7 GPRS V2

● CP 1243-1 PCC

● CP 1243-7 LTE-EU

● CP 1243-7 LTE-US

● CP 1243-8 IRC

You use the Start standard Web page (Page 1018) to access the Web pages through these

CP modules. The Start page displays all configured and installed CP modules that you have

in your local rack, but you can only access Web pages from the ones listed above.

Access to standard Web pages when Web server-enabled CPs are in the local rack

You might observe delays up to one or two minutes when connecting to the S7-1200

standard Web pages when Web server-enabled CPs are in the local rack. If the pages do

not appear to be available, or you get errors, just wait one or two minutes and refresh the

S7-1200 Programmable controller
