3 General Application The programming unit 631 is used for compilin and testing STEP-5 user-programs for the SIMATIC-S5 programmable controllers , -1lOA and -130 A/K. The PU 631 permits programs to be written in either statement list (STL) or ladder diagram (LAD) formats of representation. Using a printer, the statement list, the ladder diagram and the cross reference list may be printed out. The built-in EPROM-programming unit enables programs to be stored on EPROM-modules.

10 Connections The mains connection and the mains switch are located at the rear of the unit. The connection to the PC, the printer connection and the receptacle for the EPROM-module are located on top of the PU 631 under a cover. Heceptacle for EPROM-module PC-interface Printer connection

11 Principle of operation The PU 631 is equipped with a program memory (PU-memory) with a capacity of 4K statements. The built-in backup battery retains the program for a period of 30 minutes after the PU has been switched' off. In the on-line mode of operation a PC S5-130 may work either with its own EPROM-memory or with the PU-memory. The PC ~5-110~/ 010 can only work with the PU-memory in the on-line mode. To prevent malfunctions of the controller during on-line operation (PC with PU-memory) only complete networks (or basic software modules in the case of STL) may be transferred to the PU-memory during program inputting or alteration. This is achieved in the PU 631 with an intermediate buffer storage. A network element or statement which was inputted, appears initially in the input field of the screen. After depressing keys or, the statement is transferred to the intermediate buffer. After a completed input or alteration of a network, the contents of the intermediate. buffer must be transferred to the PU-memory by pressing key. Note: During off-line operation the transfer from the intermediate buffer to the PU-memory is done automatically as soon as the intermediate buffer is full. Hence key m needs only to be depressed at the end of program inputting. Siemens Distributor

13 Program inputting Call function selection menu with Select PU-function Inputting in LAD Inputting in STL - - Start of program if a program is stored in the PU-memory. EM is displayed in input field if the PU-memory has been cleared. Start inputting Before inputting, select required point in program (see program outputting, page 18) Example: LAD: 4 STL: AI 1.1 Note: During inputting, all correction functions are possible (see program correction, page 20). When using LAD, the networks may be inputted continuously. A new network is started, if after an output, a contact or the beginning of a parallel branch are programmed. If instead of key a, key m is pressed then only those networks which are stored up to the statement pointer, are trans- ferred to the PU-memory. Siemens Distributor

Note: If at the end of a correction key is pressed instead of key, then the corrections are not transferred to the PU-memory. Once correction has been started, functions may be overwritten and statements added or erased, in any desired combination. Furthermore, positioning is possible with keys and.

21 Inserting networks use positioning keys or search run (see Program outputting, page 18); The statement pointer is now located at the network, in front of which the insertion is to be made. press "Begin inserting a network" enter only a complete network (see Program inputting, page 14) end correction Note: When inserting networks, the same rules apply as for inputting of programs. Erasing networks use positioning keys or search run (see Program outputting, page 18); The statement pointer is now located at the network which is to be erased. Alternatively: The function "Erasing a network" may be discontinued: Siemens Distributor The network is erased directly in the PU-memory.

22 Examples for corrections in LAD Basic rules for the correction of parallel branches \ 1. TO an existing, only parallel branches also with may be added. If a series contact is to be added to an existing parallel branch, then the statement must first be converted into (see example 4, page 25). This sequence of statements is only possible with PC A/K. \ 2. If a contact is to be added to a parallel branch whlch was programmed without and, then before doing so, the and termination \ j of the parallel branch must be inserted. (see example 3, page 24).

23 Example 1: Inserting a series contact Example 2; Inserting a contact in parallel with all other contacts Example 3: Inserting a contact after a parallel branch Siemens Distributor

24 Example 4: Inserting a series branch into a parallel branch which was programmed with. Example 5: Inserting a parallel branch to a part of the existing contacts.

SIGNATJ STATUS Example: I 1.1 End function This function is only possible in operating mode 21 "PC WITH PC-MEM" (only with PC S5-130A/K) or 22 "PC WITH PU-MEM". In each case the signal status of an input (I), an output (Q), a flag (F), a timer (T) or a counter (C) may be interrogated. Notes: If the status display is to be carried out in operating mode 21 "PC WITH PC-MEM" and with the switch on the CPU in the "CYCLE" position, then the function "Transfer contents of PC-memory into PU-memory" (page 35) must be carried out first if the PU-memory does not contain the same program as the PC. In operating mode 21 "PC WITH PC-MEM" and 22 "PC WITH PU-MEM" and with the switch on the CPU in "CYCLE" position, signal status display is only possible, if the operand is contained in the program. With PC S5-110A/-010 signal status displays' are only possible if the switch on the CPU is in the "CYCLE" position. 30 Siemens Distributor

Put switch on CPU to "STOP" positon. Example: RQ 3.1 The current signal status is displayed. Notes: With the function "forcing", outputs (Q), flws (F) and timers (T) may be switched to I a desired signal status. When forcing-outputs or flags, depending on the type of operation progrannned (e.g. = ), the following reaction is obtained: Operation "=": As long as key is pressed, the selected output or flag will carry "1" signal; When releasing the key, "0" signal. Operation "S": When pressing key, the selected output - or flaq will carry. "1" signal, which is self-holding. Important! Forced outputs or flags must be reset to "0" signal. Operation "R": When pressing key, the selected output or flag is reset to "0" signal. Operation "SET": After pressing key, the preset time value of the selected timer expires. Forcing of timers with SET is only possible once. To repeat the operation an initializing pulse must first be given on the CPU. Operation "RT": After pressing key, the selected timer is stopped and reset, provided it was started with SET and has not expired. Siemens Distributor When the function forcing ended with key, an initializing pulse is activated by the CPU. ', \. i
