6. Function blocks6.1 Manufacturer function blocks6.1.6.2 PT - Put values to NETGeneraleasyE4 base devices provide 32 function blocks PT01…PT32(PUT).The list of operands and function blocks will only include thisfunction block if the project view features a NET consisting ofat least two devices.These function blocks can be used to pass an operand, whichmust not be longer than 32 bits, to the NET. The operand valueis transferred and automatically read by the correspondingGET function block GT of another NET station.Operating principleThe operand being transmitted needs to be connected to function block input I1. To dothis, you can use the output from another function block, e.g., an arithmetic functionblock. Using a marker double word such as MD1 will make it possible to sim-ultaneously transmit 32 marker bits, M01 through M32.To transmit marker bits M01 through M96, you would need three PUT function blocks inorder to transmit marker double words MD1, MD2, and MD3You can trigger the transmission with a rising edge at function block input T_. In orderfor the function block to do another transmission, it would then need to detect anotherrising edge.As an alternative, you can have the device do transmissions that depend on the cycletime, i.e., by specifying the number of cycles after which the transmission should occur.This makes it possible to optimize net loads and to transmit values that are not subjectto change as frequently less often.These options are selected in the parameters for the function block.The SC function block only functions if the NET is running properly.The function block and its parametersFunction block inputsDescription Note(Bit)EN 1: Activates the function block.T_ Trigger coilWhen there is a rising edge, the function block will tem-porarily save the input value at I1 and pass it to the NET.(DWord)342 easyE4 11/18 MN050009 EN www.eaton.com
