Table 2-1 Parameters for power modules
PM-E DC24..48V/
Diagnostics: No load voltage
Diagnostics: Fuse blown
Voltage type
The power module PM-E DC24..48V/AC24..230V (6ES7138-4CB11-0AB0) is not a direct replacement for the device with
1
order number 6ES7138-4CB00-0AB0 for AC applications, because the supply voltage must be set to either AC or DC. In
the case of DC applications, the new module does act as a direct replacement because the default setting of the new
parameter is "DC". If you want to replace the device with order number 6ES7138-4CB00-0AB0 in AC applications, you
have to create a new hardware configuration and set the value "AC" in the "Voltage type" parameter.
The parameters are explained below.
Diagnostics: No load voltage
Use this parameter to enable a diagnostic message because there is no load voltage.
If there is no load voltage, only the diagnostic message of the affected power module is sent
to the DP master. The SF error LEDs of all modules in the relevant voltage group light up.
Diagnostics: Fuse blown
Use this parameter to enable a diagnostic message because of a blown fuse.
If a fuse has blown, only the diagnostic message of the affected power module is sent to the
DP master. The SF error LEDs of all modules in the relevant voltage group light up.
Voltage type
Use this parameter to select the load voltage that is connected to the power module: Direct
(DC) voltage or alternating (AC) voltage.
This enables the correct diagnostics to be obtained when the load voltage fails or a fuse
blows.
