HITACHI LPF240A Communication module

The IMFEC11 module continuously monitors smart transmitters to provide status reports. The module sends transmitter status data to the controlling module (MFP/MFC). Access this data from the controlling module by viewing the module summary display on the operator interface. From the module summary display, call up the I/O SLAVE status report. When the function block listed (within the I/O SLAVE status report) contains a smart transmitter definition function code, that status report applies to a smart transmitter connected to an IMFEC11 module. The status report will display specific smart transmitter error codes when an error occurs. The status report lists the following: I/O SLAVE ERROR NUMBER (#), SLAVE ADDRESS (#), BLOCK NUM. (#) Table 5-2 lists smart transmitter error codes and their meaning. For corrective action, refer to the product instruction for the smart transmitter in error.

A communication failure 

will occur if a configuration download is attempted to a transmitter whose configuration lockout jumper is set to the lockout position. Each smart transmitter has its own function block. If a smart transmitter communication failure occurs, its function block appears in the I/O SLAVE report listing. NOTE: The configuration lockout jumper (on the transmitter) prevents the transmitter from being configured. Transmitter configuration and operation can be monitored, but the transmitter configuration cannot be changed from any source. Refer to the smart transmitter product instruction for information about using the lockout feature.

Missing I/O Module Error

 A missing I/O module error (no FEC response or wrong type) occurs when the IMFEC1
address (set by dipswitch S1 on the module) does not match the I/O module address in the control module configuration (function code 132). This error appears in the status bytes of the control module (bytes three through five). A missing I/O module error sets byte three equal to 03 and bytes four and five equal to the block number of the missing I/O module. A missing I/O module error also occurs if the I/O module and control module do not share the same I/O expander bus. To correct a missing I/O module error: 1. Remove the module and check the setting of address switch S1. It should match the I/O module address set in function code 132 in the control module configuration. If the I/O module addresses match, go to Step 2. If the I/O module addresses do not match, correct the I/O module addressing error.
