MicroLink: Operator Interface Terminal to move through the different screens of the MicroLink system easily. The HELP key on the keyboard provides instant access to helpful information tailored for most user screens. The system also has a special diagnostics section with information about the status of the hardware. When the MicroLink system asserts a stop output, a section of the screen shows that the stop is active.
MicroLink: Operator Interface Terminal mode, so the arrow keys are only effective in edit mode. The arrow keys will not change anything when the cursor is not present unless they are used with the CONTRAST key (Section 2.8). 2. BASIC MICROLINK INTERFACE The MicroLink system is designed to facilitate the operation of the press to which it is attached. The operator terminal has the job of conveying information to the user and providing a method of entering information in the system.
MicroLink: Operator Interface Terminal One usage of soft keys is for screen navigation. If the text on the display next to a soft key is a screen name, then pressing that soft key will pull up that screen. For instance, pressing the soft key next to the label that says Counter will bring up the screen with the counter information. 2.7 HELP Key The HELP key brings up a special screen that explains some of the information about the system.
MicroLink: Operator Interface Terminal you need to leave a blank space in your description, press the Space soft key. The Cursor Left and Cursor Right soft keys can be used to position the cursor in the letter description. This is typically used to go into a description and change a single letter without entering the entire sequence of letters again. The Abort Edit soft key will exit the edit text system without applying any changes. The menu-tree for the MicroLink system is shown in Figure 2.2.
MicroLink: Operator Interface Terminal The flush mount option allows the system to be located in a control enclosure with other press electrical systems. The advantage of this mounting arrangement is that all of the press electrical systems can be located in one central area for easier operation. Another advantage of this option is that the system can be installed within a custom made enclosure. The dimensions for flush mounting the MicroLink system in a panel are shown in Figure 3.1. 3.
MicroLink: Operator Interface Terminal The second mounting option is to install the MicroLink system in a separate enclosure that can be purchased from Link Systems. This typically allows the system to be mounted closer to the press bed, which helps the user to see the screen more readily and to more easily use the information from the unit. The physical dimensions of this enclosure are shown in Figure 3.2. The MicroLink system mounts in the door of the enclosure, which is hinged on the lower edge.
MicroLink: Operator Interface Terminal Figure 3.3: Wiring Connections Inside the MicroLink Unit The MicroLink unit has an optional counter input that is used only if there is no MultiSet system on the back access cover. The MultiSet system has a dedicated “Top” input that performs the function of the counter input when the MultiSet system is installed. The input connector inside the MicroLink unit is the green four-pin connector next to the black keypad connection.
MicroLink: Operator Interface Terminal of the MicroLink system. “IN3" is for future product expansion and is not currently used. The other four pin connector in the MicroLink unit is for the on board relay. If there is no air adjust or air adjust and slide adjust boards installed, this relay will function as a stop relay. When the counter limits are reaches, this relay will send a stop signal to the press control. There are two sets of relay contacts available. One set is normally open.
MicroLink: Operator Interface Terminal LinkNet manual for more information. Date / Time - The correct date and time are entered like any other value in the MicroLink system. Position the cursor on the value to be changed, type the new value, and press the ENTER key. 4. CONFIGURATION The MicroLink unit has a configuration screen that allows the supervisor to change some basic settings.
MicroLink: Operator Interface Terminal supervisor to configure the access code system. See Chapter 6 for more information. Pressing the “Serial Ports” soft key brings up a screen similar to Figure 4.2. This screen shows each of the five communication ports in the MicroLink unit. The soft keys on this screen are used to configure the communication tasks, such as a roll feed interface, a LinkNet connection, or a programmable logic controller (PLC) interface.
MicroLink: Operator Interface Terminal The stop condition will be output in one of two ways. If there are no air adjust board or no air adjust and slide adjust boards installed, the stop relay in the MicroLink terminal will be used to signal the stop. The wiring of this relay is described in Section 3.2.
MicroLink: Operator Interface Terminal soft key. The Change Limit soft key allows you to enter a new number for the limit. The Change Count soft key allows you to enter a new number for the current count. The Change Setting soft key will switch the state between on and off. 5.1.4 Scrap Counter This special counter tracks the number of bad parts and it requires direct input from the operator. The MicroLink system counts parts based on a “Top of Stroke” input.
MicroLink: Operator Interface Terminal same values are recalled each time a job is performed. time and it will not change unless the job is explicitly erased or overwritten. The job storage and recall functions for the MicroLink system are on the “Jobs” screen, which is found by pressing the Job Setups soft key on the main “Options” screen. After pressing this soft key the screen will look similar to Figure 5.3 5.2.2 Recall Job The Recall Job soft key brings up a screen similar to Figure 5.
MicroLink: Operator Interface Terminal screen that reports the status of any auxiliary equipment. The “Feed” soft key on that screen will bring up a screen similar to Figure 5.6. This screen allows the user to change the feed length and the feed speed by entering numeric values on the appropriate lines with the RUN/PROG key in the PROG mode. The feed length can also be adjusted in small increments by using the Micro Adj Up and Micro Adj Dn soft keys.
MicroLink: Operator Interface Terminal key switch in the PROG position. From the main “Options” screen, press the Diagnos soft key. On the diagnostics screen, press the “Config OIT” soft key, which is only present when the RUN/PROG key is in the PROG position. The MicroLink screen will pop up a window that tells you to “Enter Pass Code.” This is a special pass code that is set by Link Systems and is included separately from this manual for administrative control.
MicroLink: Operator Interface Terminal a valid access code, which takes the “Exclusive” mode another step. A user must have the RUN/PROG key in PROG mode and have the access code of a user group that has been authorized to edit that particular area before they can edit a field. setting of the functional mode of the RUN/PROG key determines what is required for a user to edit a field. Each of the four functionality settings is briefly described below and more detail is given in the subsections that follow.
MicroLink: Operator Interface Terminal After a user has entered edit mode with a valid access code, the MicroLink system remains in edit mode while the user is making changes. The system must leave edit mode when the user is finished with their changes. This logout operation can be done either by the user or automatically by the MicroLink system. The user can leave the edit mode explicitly by pressing the contrast key on the keypad (see Section 2.8).
MicroLink: Operator Interface Terminal however, the user group can be disabled without changing the rest of the configuration by setting this to “No”. 6.4.4 User Configuration: Permissions The permissions section of the screen is used to set the level of access for a particular group. The list of areas in the permissions section corresponds to the areas that require an access code. Each user group can be given clearance for a particular area by choosing “Y” (yes) or denied access by choosing “N” (no).
MicroLink: Operator Interface Terminal The next two lines indicate whether the last memory recall of the job information and of the machine information were successful. These lines will say “Ok” under normal operation. The date and the time are given on this screen also. 7. DIAGNOSTICS The MicroLink system includes diagnostic features to help solve problems with the operation of the system.
