basicbill Posted February 25, 2006 Report Posted February 25, 2006 Hi, I recently found enough $ to purchase 2 ethernet modules for our 90-30's. They have 311 cpu's in a 5 slot base. These are being used in a college environment for sporadic training purposes. The installation routine seems pretty straight forward; using VersaPro and serial connection. I noticed a limitation on the cpu firmware. Where can I find that information? Also, I noticed that there is no mac address, so I have to infer that the static IP address is programmed into the firmware during installation. One last thing....does anyone have any suggestions regarding protection online ie: firewalling. Any pointers regarding installation would be welcomed. Thanks, Bill W. Quote
Steve Bailey Posted February 26, 2006 Report Posted February 26, 2006 The manual GFK-1541 lists compatibility as follows: The CPU must be at v 6.50 or higher for full functionality. The power supply must be IC693PWR321 rev K or newer, or IC693PWR322 or IC693PWR330. The MAC ID is printed on a sticker on the circuit board. The label calls it "Default Station Address". You can enter a static IP address using the hardware configuration utility in VersaPro. Quote
basicbill Posted February 27, 2006 Author Report Posted February 27, 2006 Hi Steve, Thanks for the info. Our power supply is a IC693PWR321AA. Obviously this is much too old. My question is this.... Will the ethernet module still install? We are only using a single 120 volt input card and a single 120 volt output card so we are nowhere near maxxing out the power supply. The ethernet module is listed as drawing 700mA. The IC693PWR321AA is listed at 30 W. With our minimal output demands (firing LED's) there is plenty left for the ethernet module. Or, does VersaPro prevent it's configuration? Thanks, Bill W. The power supply must be IC693PWR321 rev K or newer, or IC693PWR322 or IC693PWR330. Quote
Steve Bailey Posted February 28, 2006 Report Posted February 28, 2006 (edited) Actually, the PWR321AA is newer than the PWR321K. The revision letters went through the alphabet A - Z, then doubled back to AA, AB, AC, etc. When adding up your power budget, don't overlook the fact that the CPU311 uses 400 mA of 5 VDC power. Also, if you need to use the serial port on the power supply, the RS232/RS485 converter uses another 125 mA. The power supply is rated at 30 watts total, but that's broken up into three components. The 5 VDC on the backplane is rated at 15 watts, the 24 VDC on the backplane is rated at 15 watts, and the auxiliary 24 VDC on the power supply terminal is rated at 20 watts. The total of the three supplies can't exceed 30 watts. In the PWR330, the 5VDC supply is rated at 30 watts, but the total consumption is still limited to 30 watts.
