Duration: Prerequisites:
5 days Delegates must have attended our 5 day Siemens S7-1200/1500 Level 1 M&T course or have similar knowledge & experience with Siemens S7-1200/1500 PLCs & TIA-Portal STEP7 v. 11, 12 or 13 software or else they will struggle with this course.
Aims:
Although the Siemens S7-1200/1500 Level 1 M&T course equips the delegate with the necessary knowledge & skills to start to maintain & troubleshoot “simple” S7 systems & applications, most Siemens S7-1200/1500 programs involve more complex instructions & Data Handling techniques. In order for maintenance personnel to be properly equipped to trace status or data values through typical programs to understand how a piece of field equipment is controlled or to identify the source of a problem, the Siemens S7-1200/1500 Level 2 M&T course covers the most commonly used supplementary instructions, gives practical experience of interpreting, monitoring & understanding more complex code & covers more advanced diagnostic tools & techniques. It will also equip applications personnel with the tools necessary to implement memory and scan time efficient control solutions.
Content:
Further Terminology, Structure & Organisation of S7 Programs • Recap the basic structure of S7-1200/1500 PLC programs •
Recap the different program formats (LAD, FBD, STL, SCL) & know how to monitor “simple” program code
•
Understand that some Blocks may have been created using other languages e.g. SCL or Graph
•
Understand the differences between the S7-1200 & 1500 CPUs, particularly the different languages available and the implications this has for coding
•
Know how to identify if other programming languages have been used & know the implications of not having the necessary software installed
•
Understand the concept of Local Data, how it is used & monitoring issues
•
Understand the principle of S7 Source Code & how & when this may be used
•
Recap the implications of using a new project as the target for the Upload of Blocks – loss of symbols, variable names & comments
Siemens S7-1200 & 1500 Level 2
Siemens S7-1200 & 1500 Level 2
Further understanding of how S7-1200/1500 PLCs handles Data (numbers) • Understand how S7-1200/1500 handles numeric values (data handling) & the toolkit available for monitoring •
Properly understand Bits (Bools), Bytes, Words & Double Words, how they relate, how they are addressed & how they occupy memory
•
Properly understand Integers, Double Integers, Real numbers, Floating Point numbers & other data types
Working with & interpreting typical STL & SCL code •
Gain further experience of reading & interpreting more complex STL and SCL program code & know how to monitor & interpret RLO & the additional status bits
•
Understand how S7-1200/1500 uses the system Accumulators when decoding logic & determining bit & word status & know how to trace conditions when monitoring a running program
•
Be aware of STL and SCL status monitoring problems & how to get around them
•
Understand the use of Jump & LBL instructions, how these alter the normal execution of the program, how to know if you are monitoring in such a zone & what happens to status information
