The RJ45 port can connect directly to another defvice (sorry, I don't know if you need a crossover cable or thru) or to a switch on your network. The AAUI port requires a transceiver to convert to whatever network media you're using. The AAUI and RJ45 ports onn the CPU module can be used to upload/download programs or for data communications via ethernet. It supports GE's SNP and SNPX protocols, and can be used to download/upload programs or for data communications. The 15-pin port on the power supply is a serial port, not parallel. Can I download my program (ladder logic and configuration) from my computer to PLC using whatever of all of this port ? The RS232 port on the CPU364 is only for maintenance and flash upgrades of the CPU firmware, not for ladder logic programming or data communications. 10BASE T using RJ 45 connector I still confuse about : 1. And in the CPU there are 3 port of communication 1. In power supply there are 15 pin paralel port communication RS-485. I want to ask about GE Series 90-30 which is using CPU 364. What protocol I can use for each port ? OK. Can I connect 10 BASE T directly to my computer ? 8. Can I connect PORT1 RS232 directly to my computer ? 7. I have to use RS485 to RS232 converter, right ? 6. For 15 pin parallel port RS 485 in power supply. Can I install versapro and Cimplicity plant Edition at the same computer ? And download my program from versapro to PLC, which at the same time Cimplicity Plant Edition is running ? 5. For human machine interface, I'm using Cimplicity Plant Edition. 15 pin parallel port RS-485 than the other port ? b. Can I download my program (ladder logic and configuration) from my computer to PLC using whatever of all of this port ? 2. I'm using PLC GE series 90-30, CPU type : 364 and PLC GE series 90-30, CPU type : 374 I want to ask about communication port from PLC to computer As I know For CPU 364 there are 3 port of communication + 1 in power supply FYI, I'm using Power (PWR331).
I still confuse when I try to apply it in the field. that is really a useful information for me.
