Safety Guidelines
Safety Guidelines
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The device/system may only be set up and used in conjunction with this documentation. Commissioning and

Properties 1
1.1 Power module PM-E DC24..48V (6ES7138-4CA50-0AB0)
Properties
● The power module PM-E DC24..48V monitors the supply voltage for all the electronic
modules in the voltage group. The supply voltage is fed in by means of the TM-P terminal
module.
● You can use all the electronic modules except the 2DI AC120V ST, 2DI AC230V ST, and
2DO AC24..230V/1A in the voltage group of the PM-E DC24..48V power module.
● Control interface (PIQ) and feedback interface (PII) in the process image for option
handling.
● The current status of the power module is stored in the status byte in the process input
image (PII). This is updated irrespective of whether the "No Load Voltage" diagnosis has
been enabled.
● The PM-E DC24..48V power module is suitable for fail-safe modules.
CAUTION
Only connect the specified rated load voltage of 24 VDC to 48 VDC to the TM-P terminal
module of the power module.
The connected rated load voltage must correspond to the supply voltage of the
electronic modules in the voltage group.
Maximum configuration per voltage group
The number of modules that can be connected depends on the total current of all modules in
a voltage group. This total must not exceed the maximum current carrying capacity.

Diagnostics: No load voltage disable/enable Disable Power module
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 potential group light.

Configuring 4
4.1 Configuring the address space
Address area for option handling and status byte
You can control and monitor option handling, and evaluate the status byte of the power
module using the control (PIO) and feedback interface (PII).
The address range of the control (PIO) and feedback interface (PII) depends on how the
corresponding entry in the configuration software is configured, or which entry has been
selected.
This table shows the PII feedback interface and the PIO control interface for different entries.
