A GET on a CPU 1511 that reads from a CPU 1214C and comes back with ERROR = 1 and STATUS = 8 has almost always been refused by the 1214C, and the 1214C has no code in it to blame. Two settings on the partner decide whether PUT and GET ever return data, and … Read more
Monitor a block on an S7-1500, build a watch table, and work out why a value sits there: modify against force, optimised blocks, and what STOP does.
Start search comes back empty on an S7-1200. Work through the PG/PC interface, the subnet, the flash-LED check and a CPU that loads but stays in STOP.
Get a CPU 1214C into an empty TIA Portal project: read the order number off the front, pick the firmware the bench CPU can take, and set the device name.
A first SCL block is two statements long – FC10, for a CPU 1516-3 PN/DP – and the first compile of it comes back with four errors and a warning. Every one of them is a ladder habit typed into a language that reads like Pascal, and the compiler is describing each habit accurately, in … Read more
A CPU 1516-3 PN/DP in RUN on the filler, a SIMATIC memory card behind its front flap, and no project file on any laptop in the building. An S7-1500 upload – online, Upload device as new station (hardware and software) – and about three minutes later an empty project holds the rack, every block with … Read more
