Note that if you the iocshLoad command you can provide all the macro values without all those calls to epicsEnvSet().

If the only problem with this method is the code duplication in each IOC then it's best to move the database into templates in a support module. Then all the IOC has to do is include them in a substitutions file. You could have one template per module type. And if there is common database code between modules then separate that out into common template files that are included in the per-module templates.
Then in the IOC startup script you may have a large list of calls to drvModbusAsynConfigure in order to setup the modbus ports for different address ranges. You can also put this in the support module, and just include it in the IOC st.cmd, passing in macros as necessary. For example, this is what I do for one of my applications for the Moxa ioLogik modules:
#E1214 Unit (6 DI and 6 Relay) epicsEnvSet("IP_ADDR","192.168.200.177:502") epicsEnvSet("IP_PORT","m1ip") epicsEnvSet("PORT","m1") < $(MOXA)/st_scripts/st_common.cmd
Where st_common.cmd is just a list of calls to drvModbusAsynConfigure. You may or may not need a different list for each type of module, depending on the modbus registry maps.
