1C31122G01模拟量输入卡,1C31122G01使用过程
HE693SNP232 SNP到RS-232适配器配有两个端口。15针“SNP”端口插头直接进入CPU机架电源上的PLC编程器端口。SNP适配器的电源为
直接从编程端口提供（最大100mA@5VDC). 9针RS-232端口连接
到任何RS-232设备。HE693SNP232适配器串行端口的“引脚”定义如下。这个
指示的方向与适配器有关。
1C31122G01模拟量输入卡选择该引脚是为了允许直接连接（使用直通电缆或1对1电缆）到IBMPC/AT。几乎所有配备9针RS232端口的IBM兼容计算机都将提供与上面所示兼容的引脚。兼容性可以使用任何类型的PLC或能够控制总线的计算机作为主持人。该网络接口单元兼容：
1.Genius NIU（所有版本）位于由控制的Genius总线上时90-70系列或PACSystems RX7i，90-70系列Genius总线控制器必须具有5.4或更高版本的固件。正在升级90-70 Genius总线控制器固件至6.0版（或更高版本）强烈建议。
2.Genius NIU（所有版本）有一个或多个扩展时机架位于由Rx3i PLC控制的Genius总线上，PLC必须使用CPU固件版本2.90或更高版本。3.Genius NIU（所有版本）有一个或多个扩展时机架位于Genius总线上，由90-30系列PLC控制PLC必须使用以下CPU型号之一：-CPU366、367或374（任何版本）或-CPU350、352、360、363或364，固件版本10.0或较高的。
The HE693SNP232 SNP to RS-232 Adapter is equipped with two ports. The 15-pin "SNP" port plugs
directly into the PLC Programmer Port on the CPU rack power supply. Power to the SNP Adapter is
supplied directly from the programming port (maximum 100mA@5VDC). The 9-pin RS-232 port connects
to any RS-232 device. The "pinout" for the HE693SNP232 Adapter serial ports are defined below. The
direction indicated is with respect to the adapter.This pinout was chosen to allow direct connection (using a straight through, or 1 to 1 cable) to the IBM
PC/AT. Nearly ALL of the IBM compatible computers equipped with a 9-pin RS232 port will provide a
pinout compatible with that shown above.Compatibility
Any type of PLC or computer capable of controlling the bus can be used
as the host. This Network Interface Unit is compatible with:
1. When a Genius NIU (all versions) is on a Genius bus controlled by
a Series 90-70 or PACSystems RX7i, the Series 90-70 Genius Bus
Controller must have firmware version 5.4 or greater. Upgrading
the 90-70 Genius Bus Controller firmware to version 6.0 (or higher)
is strongly recommended.
2. When a Genius NIU (all versions) that has one or more expansion
racks is on a Genius bus controlled by an Rx3i PLC, the PLC must
use CPU firmware version 2.90 or higher.
3. When a Genius NIU (all versions) that has one or more expansion
racks is on a Genius bus controlled by a Series 90-30 PLC, the
PLC must use one of the following CPU models:
- CPU366, 367, or 374 (any version) or
- CPU350, 352, 360, 363, or 364 with firmware release 10.0 or
higher.
