Master Module or Controller Modules) in a Process Control Unit (PCU). It gives the ability to manipulate or monitor INFI 90 module activity using an external computer with Bailey Con- trols software. Using an SPM, a computer can obtain module I/O and status data, change module mode, and configure, modify or monitor module functions (i.e., function blocks). -

DESCRIPTION AND OPERATION ® Interface computer or INFI 90 device data. • Allow a computer to perform configuration loader or mod- • ule bus monitor functions. An on-board microprocessor controls all SPM functions using programs residing in ROM. Figure is a block diagram of the SPM. - Page 19 DESCRIPTION AND OPERATION If the computer specifies a read operation (e.g., read block out- put, read problem report or read default block), the SPM receives the data from the addressed INFI 90 module and stores it in RAM. The microprocessor can output this data through its serial ports when the computer requests it.

Page 22: Module Bus Data
DESCRIPTION AND OPERATION ® MODULE BUS DATA An SPM receives and interprets commands from a computer. From these commands, it generates and sends command mes- sages to an INFI 90 module. Programs permanently stored in ROM are run to accomplish SPM functions. Execution of a specified program generates the module address and instruc- tion code (i.e., command code) an INFI 90 module requires to accomplish the computer directed function. -
Page 23: Power
DESCRIPTION AND OPERATION The message code (i.e., command code) determines the func- tion the receiving module is to perform. After receiving and interpreting a message, a module responds with a reply mes- sage. This message contains a data field with either an acknowledge or the requested data. -

DESCRIPTION AND OPERATION ® do not match, the microprocessor stops resetting the MFT causing a time out to occur. If all tests pass, the SPM initializes all RAM memory locations and begins to execute computer commands. It also sets the front panel LED to solid green to indicate that the module is on-line and operating correctly. -

DCE to begin transfer of data. For the SPM, this signal is NOT used by SPM software. When connecting Bailey Controls equipment, jumpers (JP3 and JP5) tie this line active high to continuously enable the serial inter- face circuits (i.e., ACIAs). - Page 26 Since the SPM does not use the RTS signal, it generates the CTS signal while the MFT is in its normal state and the ACIA is initialized. For Bailey Controls software, this line must be con- tinuously enabled. Jumpers (JP11 and JP12) tie the line to +15 VDC to continuously enable the output.
