FAQs - General Subjects
Q: How compatible is the OCS with 90-30, 90-70, and the Micro PLC?
A: The OCS is compatible with the 90-30. The HE693CDC200 contains one CsCAN port and one programming port for network devices. The OCS is not compatible with the 90-70 and the Micro PLC.
Q. Can I use Cimplicity HMI or any other HMI to connect to the OCS?
A: You can use Cimplicity HMI to connect to our OCS and the CsCAN network using a driver provided by us. We support writing as well as reading to the network. At this time, no other HMI's are able to connect to our network. From Cscape, you can monitor and modify registers on the CsCAN network and use it somewhat like an HMI in that sense.
Q: What kind of memory does the OCS use?
A: The program in the OCS runs from flash memory. The total memory break-down follows: 128KB of ladder and screen information, 256KB of RAM, 8KB of battery-backed RAM and 512 bytes of EEPROM.
Q: How long would a typical scan take?
A: The Scan-Rate shows the number of milliseconds for the scan. The Scan-Rate is the sum of the time required to execute the following items:
Scan Inputs
Solve Logic
Write outputs
Handle network communications
Handle host communication request
Process data for operator interface
This equates to the scan rate.
Q: Do you have UL or CE Mark ratings?
A: Please go here to view all of the current products with UL and CE.
Q: What NEMA rating do you have?
A: The OCS is currently rated at NEMA 4-12. This corresponds to general-purpose indoor/outdoor use with protection from wash-down environment. This also corresponds to indoor use with protection from dust and non-corrosive liquid drip.
Q: Does the OCS have a real time clock (RTC)?
A: The OCS does have a real time clock.
Q: Is the on-board power supply capable of handling up to any combination of SmartStack boards?
A: Yes. The OCS employs a switching DC to DC power regulator that converts the DC input voltage (15 to 30VDC) to 5VDC, up to 2.2A. The SmartStack specification allows each card to consume up to 250mA @ 5VDC. The OCS100/200 main board consumes less than 150mA @ 5VDC. With a fully stacked SmartStack on an OCS200, the maximum load on the power supply will be 1450mA
Q: Is a 120VAC to 24VDC power supply an option for the OCS?
A: A 120VAC to 24VDC power supply is not an option for the OCS.
Q: What is the life expectancy of the keypad switches?
A: The life expectancy of the stainless steel tactile switches in the OCS keypad is 1 million cycles.
Q: Is the CAN repeater a Horner Electric product?
A: The CAN repeater (HE200CGM100) is a Horner Electric product. A CAN network (without repeaters) should be limited to a maximum cable length of 1500 feet (assuming a Baud rate of 125KHz). With three Horner Electric CAN repeaters, this limit may be extended to 6000 feet. Note: The use of standard CAN transceiver chips limits the number of physically attached devices to 64.
Q: I have the function keys acting as momentary switches to trigger a screen, ie F1 for screen 1, F2 for screen 2, etc. When I power the OCS up, screen 1 is on even though F1 is not being pushed and comes back on when I let go of any other function key. Why is that?
A: Screen 1 is the default screen. If no screens are triggered, screen 1 will show. With no screens triggered, you can scroll through the screens using the arrow keys. If you are wanting to trigger to a screen, like screen 50, and scroll around from there, you will not be able to scroll from a triggered screen using the arrow keys and will instead have to implement ladder programming to do so. For example, you can make two function keys be your arrow keys. With each push of a function key, increment a counter that will trigger the next or previous screen. There are numerous ways to do this.
