B-204 M0-M1 Files and G Files Publication 1747-6.22 Capturing M0-M1 File Data The first two ladder diagrams in the last section illustrate a technique allowing you to capture and use M0 or M1 data as it exists at a particular time. In the first figure, bit M0:2.1/1 could change state between rungs 1 and 2. This could interfere with the logic applied in rung 2. The second figure avoids the problem. If rung 1 is true, bit B3/10 captures this information and places it in rung 2. In the second example of the last section, a COP instruction is used to monitor the contents of an M1 file. When the instruction goes true, the 6 words of data in file #M1:4.3 is captured as it exists at that time and placed in file #N10.0. Specialty I/O Modules with Retentive Memory Certain specialty I/O modules retain the status of M0-M1 data after power is removed. See your specialty I/O module user’s manual. This means that an OTE instruction having an M0 or M1 address remains on if it is on when power is removed. A “hold-in” rung as shown below will not function as it would if the OTE instruction were nonretentive on power loss. If the rung is true at the time power is removed, the OTE instruction latches instead of dropping out. When power is again applied, the rung will be evaluated as true instead of false. ! B3 ] [ 0 M0:2.1 ] [ 1 M0:2.1 ( ) 1 ATTENTION: When used with a speciality I/O module having retentive outputs, this rung can cause unexpected start-up on powerup. You can achieve non-retentive operation by unlatching the retentive output with the first pass bit at powerup: S:1 ] [ 15 B3 ] [ 0 M0:2.1 ] [ 1 M0:2.1 (U) 1 M0:2.1 ( ) 1 This rung is true for the first scan after powerup to unlatch M0:2.1/1.
M0-M1 Files and G Files B-205 G Files Some specialty I/O modules use G (configuration) files (indicated in the specific specialty I/O module user’s manual). These files can be thought of as the software equivalent of DIP switches. READ CONFIG ONLINE CONFIG F1 F2 The content of G files is accessed and edited offline under the I/O Configuration function. You cannot access G files under the Monitor File function. Data you enter into the G file is passed on to the specialty I/O module when you download the processor file and enter the REM Run or any one of the REM Test modes. Configuring G Files The G file is configured as part of the I/O configuration procedure for the processor file. After you have assigned the specialty I/O module to a slot (the procedure is the same as assigning other modules except that you must specify the ID code of the specialty I/O module), the following functions appear at the bottom of the screen: MODIFY RACKS MODIFY SLOT DELETE SLOT UNDEL SLOT EXIT F4 F5 F6 F7 F8 F9 This is the starting point for configuring the G file and other parameters of the specialty I/O module. Complete the following steps to create and monitor the G file: 1. Press [F9], Specialty I/O Configuration. A screen similar to the following is displayed: I/O CONFIGURATION FOR:EXAMPLE RACK 1 = 1746-A4 4-SLOT Backplane RACK 2 RACK 3 = = SPECIAL CONFIG FOR SLOT: 1 SLOT *0 *1 *2 *3 4 5 6 7 8 ESC exits C Module's ID Code: Maximum Input Words: Maximum Output Words: Scanned Input Words: Scanned Output Words: M0 Length: M1 Length: `G' File Size: ISR Number: ESC exits 12705 0 0 0 0 0 0 0 0 Press a function key ISR NUMBER F1 MODIFY G FILE F3 ADVNCD SETUP F5 G FILE SIZE F7 2. Press [F7], G File Size, then specify the number of words required for the specialty I/O module. SPIO CONFIG 3. Press [F3], Modify G File. The content of the G file appears in the display area.
