How to avoid Common Timer Instruction Issues in S7-1200/1500 PLCs?

July 25, 2025

When programming timer instructions in Siemens S7-1200/1500 PLC systems, engineers frequently encounter several implementation challenges. This article identifies three typical problems and provides effective solutions to ensure proper timer operation. Common Issue 1: Excessive Background Data Blocks The IEC timer instructions in these PLCs require individual background DB blocks for each instance. When projects use numerous timers, this leads to an unmanageable proliferation of data blocks. Recommended Solutions: 1. For FB blocks, store multiple timers in the static variables section to share a single background DB 2. For FC or OB blocks, create a global DB containing an array of IEC_TIMER data type elements Common Issue 2: Non-Functional Timers Timers may fail to initiate timing even when the enable condition is active. Solution Approach: Always connect the timer's Q (output) or ET (elapsed time) parameter to a valid variable. This connection is required for proper timer operation. Common Issue 3: State Machine Timer Problems When using timers within SCL Case statements, they often fail to reset during state transitions. Recommended Solution: Restructure the program to: 1. Place timer declarations outside the Case statement 2. Only control the timer's IN (enable) parameter within each state Implementation Guidelines Problem Category Solution Application Context Multiple DBs Use shared DB approaches High timer count applications Timer not running Connect output parameters All timer implementations State machine issues Externalize timer control SCL programming Best Practices For complex applications, the FB static variable method provides the cleanest implementation Always verify timer output connections during initial testing Maintain timer declarations separately from state-specific logic in SCL programs Additional Recommendations Test timer behavior thoroughly in a simulation environment before deployment to identify and resolve these issues early in the development cycle. Conclusion Proper timer implementation is crucial for reliable automation sequencing. By addressing these common pitfalls, engineers can develop more robust and maintainable PLC programs.
