接口测试
I/O扩展器总线测试检查
以下是接口组件。
•I/O扩展器总线接口。
•双端口静态RAM(ASI模块读/写和控制器读/写)。
•控制器和ASI模块握手。
执行以下步骤检查I/O扩展器总线接口操作:
1.将FC 217的规范S1调整为指示I/O的10
扩展器总线测试。此外,将规范S2调谐到块
ASI模块FC 215的地址。设置所有其他规范
设置为默认值并发送此块。
2.监控FC 217,输出N+4以确定
I/O扩展器总线。
如果块N+4为0000,则测试成功。
如果块N+4为2000,则测试失败(数据传回
不正确)。
有关FC 217错误的更多信息,请参阅编写器
功能代码应用手册。功能测试为:
完成如果IMASI23模块不能正常工作,
退回修理。

Interface Test
The I/O expander bus test checks for proper operation of the
following interface components.
• I/O expander bus interface.
• Dual port static RAM (ASI module read/writes and controller read/writes).
• Controller and ASI module handshaking.
Perform the following steps to check I/O expander bus interface operation:
1. Tune specification S1 of FC 217 to 10 indicating I/O
expander bus test. Also, tune specification S2 to the block
address of the ASI module's FC 215. Set all other specifications
to the default value and send this block.
2. Monitor FC 217, output N+4 to determine the status of the
I/O expander bus.
If block N+4 is 0000, the test is successful.
If block N+4 is 2000, the test has failed (data passed back
was incorrect).
For more information on FC 217 errors, refer to the Composer
Function Code Application Manual. The functional test is
complete. If the IMASI23 module does not function properly,
return it for repair.
Module Pin Connections
This section shows the pin connections for the IMASI23 module. The analog input module has three connection points for
external signals and power (P1, P2 and P3). Table 6-3 shows
the pin connections for P1. Table 6-4 shows the pin connections for P2. Table 6-5 shows the pin connections for P3.

Maintenance Section 7
Introduction
The reliability of any stand-alone product or control system is
affected by the maintenance of the equipment. ABB Automation recommends that all equipment users practice a preventive maintenance program that will keep the equipment
operating at an optimum level.
This section presents procedures that the customer should be
able to perform on site. These preventive maintenance procedures should be used as a guideline to assist in establishing
good preventive maintenance practices.
Personnel performing preventive maintenance should meet the
following qualifications.
• Maintenance personnel should be qualified electrical technicians or engineers that know the proper use of test equipment.
• Maintenance personnel should be familiar with the
IMASI23 module, module mounting unit, have experience
working with process control systems, and know what precautions to take when working on live AC/DC systems.
Preventive Maintenance Schedule
Table 7-1 is the preventive maintenance schedule for the
IMASI23 module. The table lists the preventive maintenance
tasks in groups according to their specified maintenance interval. Instructions for tasks that require further explanation are
covered under Preventive Maintenance Procedures.
NOTE: The preventive maintenance schedule is for general purposes only.
Your application may require special attention.
